Can't connect to Paper Server

[gonz05]

Describe the problem

I installed the container image on my Synology Diskstation 220+. I successfully can connect to the server, when I install the Vanilla server.

However, I'd like to run a Paper server. If I install the paper server, I see the server in the list of local servers. However, there is a small icon saying the version is 1.21.3 and I get an error message, when I try to connect the server. What could be the reason for this error?

If it's a client version mismatch then you might need to set PAPER_CHANNEL as described here

Thanks for the quick reply!

Following you link, I found out, that 1.21.3 is indeed the latest available version of Paper. Sad, but true.

If you set experimental channel then 1.21.4 is available.
