Blocking Calls warnings

[TarheelGrad1998]

Just found this integration....great work!

This is a common thing with integrations now, and apologies if it's already reported, but I didn't see it anywhere.

You are the first one to report this. On which HA version are you testing it? And if you disable TLS/SSL, does it work?

[TarheelGrad1998]

I'm running 2024.9.3 now, and Monitor Docker 1.19.

I'm planning to update to 2024.10 this week, so I can see if the error recurs with that. I can try disabling TLS at that time as well.

Also I should say, everything seems to work fine, I just get that error in the logs on every restart.

[ualex73]

I think the issue is in aiodocker, the library doing all the docker connectivity. I will check if I can workaround this error.

[ualex73]

I am getting closer to a solution, but Python 3.13 broke self-signed certificates ... Wasted some hours on that :-(

[ualex73]

SSL/TLS support should work again in 1.20b2

[ualex73]

It should be fixed, so I will close ticket in 7 days if nobody objects :-)

[TarheelGrad1998]

I updated to 1.20b2, then had to update my urls to https, and then it worked fine (and no more warnings). Thanks!

[ualex73]

Thanks for confirming, I will close it now :-)
