Fetch is taking very long and somehow the decrypted message can't be read

Inizia dal percorso di fetch indicato nel report: LibGit2Sharp.Commands.Fetch, Core.Proxy.git_remote_fetch e Core.Ensure, quindi riproduci il problema nel repository Balancing-Stuff usando il log allegato. Il lavoro è completato quando i fetch di repository di grandi dimensioni terminano senza l’errore segnalato "could not decrypt tls message".

Reproduction steps

• Get a repo with a size of >3GB, or even 800MB in our case yesterday was already enough (including .git-folder)
• Implement a fetch on that repo
• See how long it is taking any in some cases how it fails

Alternative way:

1. Get the S5Updater.
2. Extract it into an empty folder.
3. Start it (It will ask you if you really want to use it).
4. Set a path for the Gold-Folder (empty).
5. Remove the checkmark of "easy mode" or "einfacher Modus" at the bottom.
6. Press "Update MP Maps" (third button on the left.
7. Optional: check the "show log" if you wanna see our custom output with this error.
8. Read what the log is telling you.
9. Afterwards you can delete it and the folder you created for the gold-path again.

Expected behavior

Going through and not failing after some minutes (5+ minutes)

Actual behavior

For Reference: The S5Updater is our tool where we are using Libgit2sharp to get the content we need for our Systems. There you can see that.

It is also not happening for everyone. It could be related to the speed of the internet connection. The worse the internet is, the more likely you/we are getting a failure.

One of the needed repositories is this one: https://github.com/GhoulMadness/Balancing-Stuff

Another issue was already open, but it never got discussed https://github.com/libgit2/libgit2sharp/issues/2089
