We have a server running Plone 4 which hosts many of our sites, on one we have just noticed it is not sending any mail from PloneFormGen.
I have tried:
Recreating the form
Deleting & recreating the mailer in the form
Altering the site from address (avoiding any spam issues like sending to and from the same address)
All the other sites on this server can send mail fine from PFG, I am not really sure which log files to check but below is the last few lines of my events.log file which mentions a few things about missing adapters as far as I can tell, can someone translate this form me?:

This traceback means that your server is unable to connect mail server:
gaierror: [Errno -2] Name or service not known
It's an operating system levle failure.
DNS resolution of the mail server name failed. The reason could be
Firewalled server
Misconfigured DNS
or mistyped mail server name as mentioned above
Perhaps this site has an incorrect mail server configured at Site Setup>Mail?

Is this caused by not whitelisting any IP adresses? I can't find any information on what kind of IP comes out of the Azure ML. Is there a workaround to this issue?
That error is nothing to do with any IP whitelisting; it's related to not being able to connect to your mongo database. Check your connection string, and that your server is running. The connection string should look something like
mongodb://username:password#server:27017/yourdatabase?authSource=admin
First check it works from your chosen command prompt / shell using
mongo mongodb://username:password#server:27017/yourdatabase?authSource=admin
then change your python connection to:
client = pymongo.MongoClient("<working connection string>")

Can someone tell me what means? Is a problem of my server or their socket? If needed i can post my code.
The last line:
error: [Errno 104] Connection reset by peer
Means the client dropped the connection. I'd look into the Arduino code first.
I'm running Airflow on a clustered environment running on two AWS EC2-Instances. One for master and one for the worker. The worker node though periodically throws this error when running "$airflow worker":

When this error occurs the task is marked as failed on Airflow and thus fails my DAG when nothing actually went wrong in the task.
I'm using Redis as my queue and postgreSQL as my meta-database. Both are external as AWS services. I'm running all of this on my company environment which is why the full name of the server is ip-1.2.3.4.eco.tanonprod.comanyname.io. It looks like it wants this full name somewhere but I have no idea where I need to fix this value so that it's getting ip-1.2.3.4.eco.tanonprod.comanyname.io instead of just ip-1.2.3.4.
The really weird thing about this issue is that it doesn't always happen. It seems to just randomly happen every once in a while when I run the DAG. It's also occurring on all of my DAGs sporadically so it's not just one DAG. I find it strange though how it's sporadic because that means other task runs are handling the IP address for whatever this is just fine.
Note: I've changed the real IP address to 1.2.3.4 for privacy reasons.
Answer:
https://github.com/apache/incubator-airflow/pull/2484
This is exactly the problem I am having and other Airflow users on AWS EC2-Instances are experiencing it as well.
The hostname is set when the task instance runs, and is set to self.hostname = socket.getfqdn(), where socket is the python package import socket.
The comparison that triggers this error is:
fqdn = socket.getfqdn()
if fqdn != ti.hostname:
logging.warning("The recorded hostname {ti.hostname} "
"does not match this instance's hostname "
"{fqdn}".format(**locals()))
raise AirflowException("Hostname of job runner does not match")
It seems like the hostname on the ec2 instance is changing on you while the worker is running. Perhaps try manually setting the hostname as described here https://forums.aws.amazon.com/thread.jspa?threadID=246906 and see if that sticks.
I had a similar problem on my Mac. It fixed it setting hostname_callable = socket:gethostname in airflow.cfg.
Personally when running on my Mac, I found that I got similar errors to this when the Mac would sleep while I was running a long job. The solution was to go into System Preferences -> Energy Saver and then check "Prevent computer from sleeping automatically when the display is off."
I have a free account on PythonAnywhere from where I am trying to run the following script that locally works just fine.
I am wondering if the error I get is for technical reasons or just that PythonAnywhere forbids people to scrap from their platform for certain websites only?
Do you know of other free websites where I would be allowed to scrap anything?
