@atripp Thank you for this answer. But we check connection string and it's ok and correct. We can connect with SQLServer.
But why in logs is BuildMaster, we only use one solution ProGet. So maybe someting is wrong with confirguration in ProGet's file?

Hi,

ProGet was working until the key was replaced.(for Basic License)
Proget version 2024.21 and SQL Version 2022
Yes, in docker compose we have a connection link to SQL Server, which is on the same VLAN and we haven't any firewall rules as well.
