Machine not working in FRA region, perfectly working in AMS region

Originally working in AMS region - deployed machine number of times - all worked perfectly.

Decided to move machines to FRA region (“closer”) and then problems started - deployment was succesfull, but access to web application every time ended up with HTTP 502.

Only when remembered that I moved to FRA, and destroyed that machine and restored AMS as target region, everything started working again w/o problems.

Did anyone else experience this kind of problem tonight?
