Git hangs on cloning

[TCH]

I've upgraded my system from Devuan 2 to Devuan 4 and now git hangs on cloning:

# GIT_TRACE=1 GIT_CURL_VERBOSE=1 git clone --verbose https://github.com/punesemu/puNES

02:04:36.418257 git.c:444               trace: built-in: git clone --verbose https://github.com/punesemu/puNES

Any tips where should i look, what should i check?
(The problem is not with the repository: it hangs on all repositories. Edit: Also, curl works, so it's not an issue of curl.)
