Fout: Bad Gateway 502 bij het verzenden van uitnodigingen

Unfortunately, I am still not able to invite people to my forum since 4 hours.:thinking:
It makes no difference if I import them via CSV (there it says ā€œINVALID EMAILā€) or if I want to send someone an invitation via mail. I tried to set the domains on the whitelist, but this also did not helped.
Is there any news about bigger server problems

, or what could it be? :upside_down_face:
