I have a WordPress site hosted on Google Cloud, and was working very well.
With no apparent motive, stoped working and I can't access to it, neither the front panel or admin panel.
I can't access via FTP o SSH console.
The VM on Google cloud still running as far as I can see.
Errors I get:
When trying to access de website on Google Chrome:
ERR_CONNECTION_TIMED_OUT
When trying to access FTP via FileZilla:
Error: Connection timed out after 20 seconds of inactivity
Error: Could not connect to server
When trying to access SSH:
Connection via Cloud Identity-Aware Proxy Failed Code: 4003 Reason:
failed to connect to backend You may be able to connect without using
the Cloud Identity-Aware Proxy.
i just want to update this issue.
The problem was that the memory quota.
I've increased the amounth of memory, restarted de VM and all went back to work.
Thanks
This page with SSH troubleshooting steps might be able to help you.
The issue could be solved by trying these troubleshooting steps. I think it is likely that the first one might be the cause of your issue since you mentioned it did work before.
Does the instance have a full disk? Try to expand it!
Is the firewall correctly setup, check your firewall rules and ensure that the default-allow-ssh rule is present.
Check your IAM permissions, do you have the roles required to connect to the VM?
Enable the serial console from your instance settings, connect and review the logs, they might give you some useful insights.

I am having a mild panic attack and could use some help.
I was emailed by Google telling me I need to change my machine type in my VM Instance. So I logged in, it told me I needed to stop the instance to make that change. I stopped the instance and then realized I'm not using the deprecated F1-Micro, so I just hit Play to restart the instance.
It restarts, has the reassuring green symbol, but my wordpress site can't be accessed.
I tried connecting via SSH and it seems like the data is there, I can navigate to the wordpress folder.
Can someone please advise on what I need to do to get the site running?
Thanks!
EDIT: More Info
Checking status of NGINX server shows it is "active (running)"
When visiting the web address, it loads for a very long time and then goes to an error page that just says "This site can't be reached the site took too long to respond. try checking connection and the proxy and the firewall. ERR_CONNECTION_TIMED_OUT"
I found the issue.
The Google documentation suggests your IP address will remain. Whether that is standard or not, my IP address changed, so once I updated my DNS records I was back online.
I changed my VM instance from "F1-micro" to "E2-micro". When I then restarted my machine, I couldn't access my webpage using the domain name, the webpage just shows an "Error 521" code - showing that my browser is working, CDN is working but the host has an erorr. When I paste the VMs IP address into my webpage, however, it show's the "Apache2 Debian Default Page".
Can somebody please help me with this?
The Error 521 message is caused by one of two situations:
First, check whether your WordPress site’s server is down. Even if everything else is configured properly, if your WordPress site’s server is offline, Cloudflare simply won’t be able to connect.
Second, your web server might be running fine but blocking Cloudflare’s requests. Because of how Cloudflare works, some server-side security solutions might inadvertently block Cloudflare’s IP addresses.
Cloudflare is a reverse proxy, all the traffic coming to your origin server will appear as if it’s coming from a small range of Cloudflare IPs (rather than each individual visitor’s unique IP address). Because of that, some security solutions will view high traffic from a limited number of IP addresses as an attack and block them.
Please check this link out in order to fix error 521 for Cloudflare and WordPress.
Turns out this problem was caused by my having installed the Debian Apache server package and it is causing collisions between it and the Apache shipped in the stack. Bitnami Stacks are completely self-contained and run independently of the rest of the software or libraries installed on your system.
So to fix this, all I had to do was run the following commands:
sudo systemctl stop apache2
sudo /opt/bitnami/ctlscript.sh restart
I've tried two methods to connect my Shiny app to a BigQuery table as its source data:
Hadley's bigrquery, and
Mark Edmondson's BigQueryR
They're both failing the same way, so it's clearly a DFU error.
In each case, when I execute the appropriate command to establish the authorized connection (gar_auth_service(json_file = /path/,scope = 'https://www.googleapis.com/auth/bigquery' and bq_auth(path = /path/, respectively), I get this:
This site can’t be reached localhost refused to connect. Try:
Checking the connection Checking the proxy and the firewall
ERR_CONNECTION_REFUSED
This error comes after what appears to be a normal Google login process in the browser. The error page is hosted at localhost:1410, if that's any help.
In the Console, I have:
Created a VM instance (Ubuntu 19)
Successfully installed R, RStudio, and Shiny
Successfully logged in to RStudio in my GCP instance (from the browser, obviously, using the Externa IP I reserved in GCP)
I've also already created a BigQuery table in the same project, and successfully connected to it from an R script on my local machine.
I'm trying to get that same R script to run grom my Google Compute Engine instance.
Have I provided enough details to ask for help? If not, let me know what else I should provide. I'm walking through teaching myself GCP right now, and I'm quite the novice.
Thanks!
To bypass this issue, try connecting to your Ubuntu 19 instance using Chrome Remote Desktop on your Compute Engine instance as documented here.
Chrome Remote Desktop allows you to remotely access applications with a graphical user interface from a local computer instead of using the External IP. For this approach, you don't need to open firewall ports, and you use your Google Account for authentication and authorization. I've tried and I was able to connect both Shiny Server and to the RStudio.

SSAS is running on a hosted server. No domain.
Able to connect with anonymous authentication, but when basic is enabled, neither SSMS or Excel will connect.
Error from SSMS is "The remote server returned an error (401). Unauthorized"
Credentials are set up on the remote machine as DOMAIN:443
Credentials have admin privileges on the server.
Excel says "connection cannot be made to remote machine or SSAS is not running"
HTTP or HTTPS doesn't matter.
When it connects with anonymous, no cubes are returned so it is apparently doing nothing with the userid/password. Just connecting.
When I connect via port 2383 using the same credentials, I have no problem in SSMS or Excel.
Help is GREATLY appreciated. Thanks.
This was partially solved by starting over and following the steps in this article:

Honestly, I can't pin down the exact resolution, but I believe it has to do with using a different folder structure (other than inetpub/wwwroot...) on my D drive and therefore losing the standard security configuration.
I created an OLAP folder on C:/inetpub/wwwroot and it works... with the exception of SSL which still does not work.
HTTP connects fine, but not HTTPS. Still working on that.
I use cyberduck for SFTP my website files to the server. Dreamhost is the server.
In setting up a new bookmark in cyberduck I received this error "Connection failed - EOF while reading packet." [end of file]
The website is up and working fine, http://ce-t.org
Initially I thought this error had to do with the connection opening with cyberduck. So I setup a different bookmark to test and was able to do without a problem.
I have also deleted my first attempt to setup and reset up. This did not alter anything.
Now after doing more reading, may be in one of the website files?
As you can see i am a novice.
Help appreciated.
Usually when I run into this issue, its because my pw has expired.
Try SSHing into the server and change/update your pw. After I change it, I can FTP in.
This is 3 years too late for the OP. But I had this error when trying to make an SFTP connection to hosting on a Plesk server and the solution was to:
Enable the 'Access to the server over SSH' setting for the ftp user via the Plesk Control panel.
Of course you might need to contact your hosting service to get this done if you are not managing your own server.
In my case the same error occurred due to a syntax error in the .bashrc file on the remote server.
Also note that the default account setting for an FTP user at Dreamhost might specify an FTP connection. If so, trying to use Cyberduck to connect via SFTP will generate this error message. You can use the Dreamhost control panel to edit the user's record to specify SFTP.
In my case I have used dropbear ssh server.
I replace this server with openssh server, and now i can open the sftp connection without any issues.
