Chrome on android has a feature to reduce data usage, this must use Google to proxy requests, almost certainly using a load balancer.
This appears to cause your ip address to change every time, and causes this forum to fail to log you in.
If you can't log-in, please check you're not using a data saver or other proxy device which causes your ip address to change rapidly.
We'll investigate this. We'll also be looking to switch to https too.
Thanks for your attention.
