Can’t connect to Kodi Addon Repository

I can’t seem to install anything from the Kodi addon repository (the default one). Also, the “Get more” option is vanished as well.

a. I have checked the log and it says 503 and 403/404 errors, when trying to connect to mirrors.kodi.tv and repository.xbmc.org Here is the log. https://paste.ee/p/58XUI#
With the browser, trying to visit the sites, I get a cloudflare protection prompt, is this the reason?

b. Thought it is a network issue, so I used a VPN, but things didn’t change at all.

c. I have tried on Windows, Linux, Android devices/platforms and all the versions from 15.x (isengard) to 17.x (Krypton), none could connect to the default kodi addon repo.

d. I have tried fresh installs with and without third party repos, but its still the same. No addons could be installed, from any source. The log file doesn’t have anything with any third party addon or repo.

Please help me out here.
