My docker image broke the other day, and I had to start all docker templates again, no big deal.

All of them, except 2 from linuxserver, came up online again.

They have a problem git cloning. I have also tried to git clone directly from the unraid server with the same error:

 

git clone -v https://github.com/drzoidberg33/plexpy.git /mnt/user/appdata/plexpy
Cloning into '/mnt/user/appdata/plexpy'...
POST git-upload-pack (gzip 3590 to 1828 bytes)
error: RPC failed; curl 52 Empty reply from server
fatal: The remote end hung up unexpectedly

 

I tried to change to google dns server, same result.

 

I can ping github.com fine, i just cant clone.

Just to add to this, I was helping ZataH with the docker side and it became apparent that the issue was with git cloning rather than the containers themselves, which is why it's affecting the Unraid host too.

 

From memory, he has a bonded NIC on his Unraid box, but I think it would be useful if he posted more details about his network topography.

Pfsense box running as router and dns.

All lan to wan i allowed.

 

The containers are installing fine from another docker host + It used to work on my unraid, so i dont think the issue is the physical network.

I am pretty sure the issue is on the unraid box, I just have no idea where to look

 

I have been running 6.3RC4, but I am back on 6.2.4, just to check if it had something to do with the beta release

Yeah, I was including Unraid in my all encompassing "network topology"  Post some diagnostics as well as that gives some info on your network setup within unraid.

I was tracing back to what I might have changed, since i deployed my unraid.

 

I have now found the root cause. If i change my MTU to anything other than the standard 1500, the git clone does not work

 

Both plexpy and sickrage are now working, with standard mtu

Interesting, going to remember that one....

Do you have any idea, why this is affecting git clone?

Nope...
