Working Photon server when moved to a user in Japan is unable to launch with a DNS error in the logs

ZigzaTom

People in our US office have no problem running the photon server but when given to somebody in our Japan office, there appears to be a DNS error when starting up photon. Oddly enough the log for load balancer indicates the master was started correctly, but then the game server fails with this error. The only changes made to run it on his machine was going into the photon controller config and find-replace my local IP with his local ip, and then the same on the loadbalancer game and master config files.

Hi, @ZigzaTom
Defenetly bug is in your loadbalancing config for GameServer. you've set master server address which is valid for you in US office and invalid in Japan.

best,

We simply did a find and replace of my local IP with his local IP in that config file. How would that be invalid? It also seems strange that master could start but game could not because we copied one on top of the other. Also I don't know that it matters but for whatever reason there local IPs look like 10.0.0.52 and for me local IPs have always been 192.168.1.xxx

i can not say anything without seeing of your configs and logs. Please send us e-mail developer@photonengine.com with logs, configs and reference to this topic

best,

Ok I will have him send me them when he gets in(1am there now) and I will also drop them into my folder and see if I can start with them. If I cannot see any problems then I will forward them on to the mail as requested. Thanks for your continued support on these forums!
