VueJs page is blank when using some wifi networks - networking

I'm experiencing a weird behavior on my site. I hosted a Vue ssr application on a Digital ocean droplet, I have my domain name registered with Godaddy. The Godaddy domain name was first of all pointing to a different server, I then change to dns of the domain to point it to the digital ocean droplet. Every was working fine but it stop working on it's own after some time. The domain, example.com, was now displaying a page with a red car on it (that's not my website), and the sub-domain vuejs.example.com, was loading a blank page.
I disconnected from the wifi network I was using, xxx, and connected to an other wifi network, yyy, the site works perfectly with the yyy network but
still didn't work with the xxx network.
This morning when I got up I tried accessing the site again with the xxx network and it worked but the vuejs.example.com sub-domain doesn't still work. When I open the sub-domain I get a blank page but the title of the vuejs application and the favicon are displayed normally.
Note:
1: If I change the network, the sub-domain where my web app runs will work perfectly (vuejs.example.com)
2: Using xxx network, all other sites open, so the problem is not with the Internet connection
3: I asked to friends to try to access the sub-domain, vuejs.example.com, where the vuejs app is hosted; those who accessed using the same internet provider as xxx network also had the blank page. Those who used different internet providers could open the vuejs app with no problem.
I'm sorry for the english, please let me know if something is not clear. I hope I can find a solution here.
**Edit: ** I have just noticed that certain files could not be loaded on this network but I don't know why.
All the files with response 304 are not loaded.

No access to wordpress backend anymore - "Your connection is not private"

hope you can help me because I'm losing my mind here:
A couple of months ago, I started to build my new website (WordPress, hosted on Google Cloud, deployed with "Click to deploy" and I got the domain name on Google Domains).
Everything worked fine back then. But I needed to put this project on hold.
Now I wanted to continue working on the website, and I realized the VM was stopped. I successfully re-started it and wanted to access the WP back end with the link that can be found in the Deployment Manager of Google Clouds ([IP address]/wp-admin) but it doesn't work anymore. It only says the connection is not private, and I can't access the website. I can't even get to the login form.
What I have tried so far:
Changed ephemeral IP to static external IP & connected the VM to the IP
Pointed Domain toward static external IP - as shown in any tutorial
Updated NS on Google Domains
Created DNS Zones (A, CNAME)
Installed SSL for my domain successfull
Still not working, neither the IP nor the domain (server not found).
My guess - the Domain (mk-studios.net) is not live yet, and therefore, the SSL certification doesn't work yet. If not, I messed something up, and I don't know where to look. I don't get why it worked well months ago and has stopped working now.
Does anyone have a guess? Do you need any further details?
Thank you so much in advance,
Best,
Mario
This problem may have many causes but the most common is that your SSL has NOT installed properly. I suggest you the following steps:
Make sure that your SSL works fine and reinstall your SSL.
If you have access to DB, go to *_options table and in the first two rows siteurl && home you will find your URL. In this point remove the "S" from the https:// and make it http://.
If you have other server take the DB locally an connect with WP files from fresh installation.
Also when you remove the -s from https:// visit your url with incognito mode/private mode.
I will stay here to help you.

Hosts file ignoring only one mapping, Mac Big Sur OS

I was wondering if have any thoughts/suggestions.
I am moving a site onto a new hosting and trying to preview it using my hosts file. I'm being redirected to https in all browsers - Safari, Chrome, Firefox, Brave. This is a static site with a WordPress news section.
What I have tried:
confirmed the IP I'm adding to hosts file is correct
cleared the dns cache
viewed in incognito
made sure the hosts file is not being ignored - another site I am viewing is working fine + I pinged the domain and it returned the new IP address I am trying to view but I am still being redirected
redirects are commented out in htaccess
enabling a test domain in the c panel which is also redirecting me to the live site, even on Tor
it works on my colleague's Windows machine.
Do you have any more quick ideas/thoughts as to what may be causing this? I am out of ideas now.

IIS Wordpress Not accepting connections from internet

I recently setup a wordpress website on IIS.
I configured the website and it is working on the local machine. I can browse pages and get to the wordpress admin.
I also configured IIS with the correct site binding, host name and ip address.
However from the internet I can not reach the website. It's as if the wordpress site is not listening to or IIS is not passing along traffic from the internet. And just to make sure it wasn't an issue with IIS. I setup a second website on that server that is accessible from the web. That one is working.
Any anyone has any ideas I'd appreciate it.
After doing some testing.
In this case. The wordpress site would not respond or map to the correct domain name on the main ip address of the server.
After adding a second IP address on the nic card and mapping that in IIS the website worked properly.
It was a very strange situation. It should of just worked on the main IP. But it didn't. shrug.

Google ads show on localhost but not on live web server

I have a wordpress website, which is approved by google adsense. However, I decided to move it to a home web server now. What i did so far:
I created a localhost using xampp on windows 7.
I opened a port and linked the localhost to my router external ip. (I have not linked the website to my domain yet, so i access the website by its ip)
The webiste is running well now except for the ads. They show up when the website is on localhost, but there is only a blank space when i change the website url from localhost to my router ip address.
Do you have any ideas whether this can be fixed since i could not find any info about this? Thank you very much in advance for any information shared!
When you just created a new ads in google adsense you must wait a few minutes before they will show correctly on web page.

wordpress website is being redirected to some other website

I set up my blog with wordpress cms few days ago and it was working fine, url is blog,I also noticed that it only happens only on few network connection.for e.g.: it works fine on my mobile data pack and wifi connection but in my office it got redirected to some other web page.
How and why it is happenings have already checked .htaccessand dns
and found nothing suspicious.
Seems to be working correctly. Check with your office's network administrator.
Additionally, scan your files for any spam injection.
