Your Mainnet works terrible!
Your network does not work. constantly error. check the Internet router or firewall. I tried on 3 different computers. and two phones. everywhere a different provider.
I have the same problem. Nothing helps - restarting PC, restarting Internet, clean browser cookie, changing browser.
Stop your Mainnet, resolve all issues and then start again.
The problem is with the connection infrastructure, the entry point to the system. Is not your fault, it is ours. We are working to deploy a fix. The mainnet is safe and it works, it is just hard to connect to it.
Apologies.
