MSSQL Error to Reconnect with a Public IP Address

Hello Grafana Community,

i changed my grafana server and mysql server from local ip address to public ip address and i have an “Invalid packet size, it is longer than buffer size” Error and i don´t know why. Both server are vm on hyperv and have connection to each other.

I opened the ports 1433 and 3000 in my firewall but i don´t know how to fix it.

I hope anyone can help me and i´m not to stupid.


Got it - just have to open the whole ports ( TCP 1433, 4022, 135, 1434, UDP 1434) for sql connection
