After a move to a new machine with Manjaro I cannot access the cvs web pages repositories as a project member.

$ cvs -z3 -d:ext:slawekk@cvs.savannah.nongnu.org:/web/isarmathlib co isarmathlib
connect to address 209.51.188.81: Connection timed out
Trying 2001:470:142::81...
cvs.savannah.nongnu.org: Network is unreachable

I have added my ssh key as required and membership access to svn repositories is working fine:

$ svn co svn+ssh://slawekk@svn.savannah.nongnu.org/isarmathlib
Enter passphrase for key '/home/slawekadmin/.ssh/id_rsa':
A    isarmathlib/tags
A    isarmathlib/tags/isarmathlib-1.6.4
(...)

Also, attempt to log in with ssh works as expected:

$ ssh -email is unavailable-
Enter passphrase for key '/home/slawekadmin/.ssh/id_rsa':
Linux vcs1.savannah.gnu.org 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u3 (2019-06-16) x86_64

Sorry, you are not allowed to execute that command.
Connection to cvs.savannah.nongnu.org closed.

Do you have any suggestions on what I can do to troubleshoot this?

Thanks,
