This is the public community server.
I guess it could be an issue with the redirection as the community service is served by a cluster, so according your location it redirects to your closer instance, maybe a workaround could be to detect the address of the service that serves your location, by a nslookup to iot.thinger.io or backend.thinger.io, in my case it aims to us-east.aws.thinger.io
Hope this helps
