SG throws urllib.error.URLError while connecting through shotgun API

When we are connecting shotgun through API the following error we are getting and it is not consistent always. Randomly we are getting this error, but nowadays the percentage of getting error got increased in our production.

Check if you are using the latest version of the ap library.
Also worth checking in with your IT department if the firewall could be blocking traffic.

Hi Ricardo,

Thanks for your valuable information.

How to monitor the query traffic and responses in SG? If SG request got failed where we can view the failure log details with the reason.

You should be logging from your application, you can also use a logging tool like Sentry for example.

Hello everyone, sorry for the delay. We’ve been working on this workaround to enable seamless retries when AWS server error like these happens.

I have this PR in testing: SG-35165 Retry on URLError by carlos-villavicencio-adsk · Pull Request #342 · shotgunsoftware/python-api · GitHub it would be great if anyone else can give it a try. I know it’s hard to reproduce.
