Updating CURRENT (FreeBSD 15.0-CURRENT #61 main-n273942-e8d027be6b84: Sat Nov 30 01:24:07
CET 2024 amd64) left the system in a "starnge" state: most applications accessing the net
(firefox, librewold, claws-mail) do have access problems - mostly timeout errors.

git -C /usr/src pull 

fails after a while with 

error: RPC failed: curl 56 recv failure: Operation timed out
fatal: exprected 'acknowledgements'

(git remote -v:
origin htps://git.freebsd.org/src.git ...)

I do not have any problems accessing/pulling ports repository via git.

I do not have ANY problem access git repos on an 1 week older CURRENT or FreeBSD
14-STABLE (recently updated, FreeBSD 14.2-STABLE #19 stable/14-n269714-57a7f61b13c3: Sat
Nov 30 10:20:15 CET 2024 amd64).

Is there anything to be aware of?

Thanks in advance,

oh
