Hey there @bieniu, mind taking a look at this issue as it has been labeled with an integration (brother) you are listed as a code owner for? Thanks!

[bieniu]

This problem is related to pysnmp package, not to the Brother integration etingof/pysnmp#413

[flaviut]

hi mr stale bot, this is still an issue.

[flaviut]

Looks like the pysnmp package is completely unmaintained since the start of 2020, as it only has one contributor who is no longer working on it.

I've submitted a PR at etingof/pysnmp#415

I'll try to reach out the the maintainer directly in a month if I don't hear back by then.

[github-actions]

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.
Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍
This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

Looks like a few folks (who seem reliable to me) have forked this into https://github.com/pysnmp/pysnmp/. The new library is https://pypi.org/project/pysnmplib/ on pypi. (still an issue though, until
