Unable to pull linuxserver.io dockers?


Recommended Posts

Update. DNS messed up by PiHole (I think). Set DNS in unRaid network settings, everythings all good now.

 

Running unRaid 6.2.0-beta21 I can install dockers from a number of different repositories. They seem to take a little while but that isn't the problem.  Any dockers from linuxserver.io refuse to pull, I have a notion from some comments around the internet that it could be due to an incorrect MTU value. Can anyone direct me to a solution? My Google-fu has failed me.

 

Install log below.

Many Thanks.

Same problem here (unRaid v6.1.9), however setting the DNS in unRaid network settings didn't help.

The unRaid server can download and update apps, so has access to the internet.

I think your issue might be different to mine. I don't think mine was pulling any data because the install was never managing to get addresses from the DNS thus the timeout. Where as a HTTP code 400 is according to w3.org,

HTTP Code 400 Bad Request

 

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.

 

I guess yours is only happening for linuxserver dockers like mine though? Maybe head to their forums and ask around?

Thanks for digging for the HTTP code 400 meaning. I was too lazy  :P, assuming something wrong on my side (Newbie, 1st docker).

anyway "malformed syntax" might suggest otherwise. I will ask is linuxserver's MariaDB thread or linuxserver  forums.

 

Edit: The problem is on my server. A different docker, same result:

Edit2: Installed other dockers successfully. Seems a Docker Hub problem, however it's odd that others don't have it or have a way to solve it.
