Summary
I'm unable to access any Git repository on gitlab.com over SSH today using RSA based keys, it was working fine yesterday on June 9th. Seems like other user is reporting same issue on the forum. It seems, that it works fine with Ed25519 based keys.
Steps to reproduce
$ git clone git@gitlab.com:ynezz/openwrt.git
Example Project
Any project on GitLab.com where I've access, so anything under https://gitlab.com/ynezz, https://gitlab.com/openwrt etc.
What is the current bug behavior?

What is the expected correct behavior?

Relevant logs and/or screenshots
