Github linking issue

i understand this is a recurrent problem yet it is happening again:
One can not link its unreal account to its github account in order to access to the sources.
I went under “Connected Accounts” in my unreal acount profile page and tried to link with github, entered my credentials and logged to both unreal and github.
A dialog tells me to check my mails for a confirmation mail, but i never received this mail. Checked spam folders, etc.
I tried to do this about 10 times, thinking the automated response process was down, but it doesn’t seem to get better after a few days.
Anyone has an idea what to do ?

Thank you.
