OK guys.
I am sure right now that your local DNS'es in your routers sometimes have problem or cache ip address for too long.
I will look into possibility to set static ip address of dns to 1.1.1.1
That would solve those problems once for all.
I dont understand 100%, but to give you some extra input. I tried to acces simplemining from 3 different locations (so other routers and dns) but it still gives me the same issue.
I also have miners on 5 different locations on my simplemining account.
I hope you get something out of this info..
btw i also cant reach the chat...
