[solved] Error 502 Undocumented errors: different region

Hi there,

I’m running an Elixir Phoenix app, just pushed out a deploy and now my logs are showing a:

I’ve seen that other people have run into this problem, but my case seems slightly different. My app’s region is set to Seattle (SEA) and I’m based out of Japan (NRT). All of a sudden when I look at my logs it seems to think I’m connected to a Japan (NRT) server.

I had my logs open at the time, so you can see the switch from SEA to NRT:

From the dashboard you can see that I only have one location setup:

I’ve tried turning off autoscaling, I’ve restarted the app, set the scale 0 then to 1 again. The issue seems to persist.

It was working this morning and I haven’t changed anything configuration wise with my app.

Any help would be appreciated.

Thanks.

Got the same error this morning at 8:15 GMT. Restarted and all good now.

I can confirm that whatever the issue was, it seems to be resolved.
