Or why not request for a static IP address from your provider? So instead of a dynamic IP address that could be dirty or that range could be treated as harmful or suspicious, why not a dedicated one for you?
This costs extra, so it is justified only if it is necessary for more services, especially self-hosted. Also, it does not have to be a solution to the problem, because the whole class can be blocked by that provider, not just one IP address.
As @DYING_S0UL replied, he doesn't have much knowledge about IP and doesn't know what the problem is when he uses Coinomize. I've never encountered this issue even though I sometimes use a VPN to access Coinomize. I hope that members who are good at internet technology will have helpful guidance for @DYING_S0UL.
I already said earlier, in such cases, you would have to restart the modem or the device used to connect to the ISP. It is very likely that after the restart it will get a new IP address. If it is a question of sharing connections, then there is not much that can be done because the ban probably came because of one of the users from the network. Even with a new IP, the same thing will happen very quickly.
If he is really determined to understand the problem, he can privately share his IP address with the Coinomize team, so that they can identify the problem together.
@DYING_S0UL It's enough to write in Chrome "What's my IP" to get this info.
