Thank you for answering. I already tried that. @curvefi

Answer: It sounds like you've already tried the suggested solution, but if you haven't already, it might be worth trying the old UI to see if that resolves the RPC issue. If this doesn't work, you may need to look into further troubleshooting steps, such as checking the server's firewall settings or checking the server's RPC configuration. If the issue persists, it may be worth consulting a professional for further assistance.

This is prorably rpc issue, but try old UI I think it might work
