Unresponsive DNS after trying to update filters

[Razumasu]

I've had the server running for 6 months or so now without any issues. Then suddenly it started becoming unresponsive, making all DNS checks to the server fail.

Every time it becomes unresponsive it happens right after an attempt automatically update filters. After the fail, the app needs to be restarted.

Any suggestions on what could be going on?

@Razumasu Sounds like an ungraceful handling of filter updates, and allowing for a bad state.

[imc67]

@Razumasu I have the same issues, it’s known and an update is coming:

https://github.com/AdguardTeam/AdGuardHome/issues/5661

[imc67]

@girish @nebulon Adguard Home newest version is just released.

[nebulon]

@imc67 is this issue then fixed in the latest version?

[imc67]

@nebulon yes for my 3 instances it’s stable again !

[Razumasu]

@imc67 Thanks. I just ran the update. Hopefully, this will fix it
