TimeoutError: [Errno 110] Connect call failed ('', 443)"


I am writing to bring to your attention an issue I am currently facing with multiple processes that utilize various API endpoints to retrieve data related to live streams on Twitch. These processes have been running continuously for over a year, adhering to all the limitations and rules specified in the API documentation. I would like to highlight that these tasks are executed within the AWS infrastructure.

Starting from early morning today, I have been consistently encountering the following error message across all my tasks:

I have thoroughly reviewed relevant topic(Failed to establish a new connection: [Errno 110] Connection timed out) on the forum regarding this issue, and I can assure you that no changes have been made on our end, as the infrastructure remains the same. Could there be a possibility that Twitch is currently imposing restrictions or blocking our traffic in some manner?

Your assistance in resolving this matter would be greatly appreciated.

It’s more likely that any of the nodes between you and Twitch are having an issue.

And it’s not Tiwtch itself.

Quite commonly, for example, German/Vodafone will just give up allowing taffic between German and AWS services for whatever reason.
And thats on the ISP/provider not Twitch.

So it’s not likely Twitch are imposing restrictions is more likely your ISP/provider is having and issue or something along the chain between you and Twitch.

Or it’s DNS, or it’s caching, or it’s caching of DNS


It’s always DNS :stuck_out_tongue:
