Connection between Epicgames Acc and Github acc

Hi I’m trying to connect my github account to Epic Games account but it cannot connect and the message is displayed which is that ‘the service is temporarily unavailable. Please try back later’. How can I solve this kind of problem?

p.s. Other accounts connections are same such as twitch, xbox, psn etc.

Watch this video and tell me if that did help you or not:

I fixed this problem from AdBlock Extension. I disabled it during connection and then it works. But thanks to give other solution for me
