Error connecting to SQL Server using another machine SSMS

I am getting the below error when trying to connect to SQL Server

I have searched around and ensured all settings are configured correctly, service running, rules in firewall, correct TCP, etc. It was working well however since stopped working without me changing any settings.

SQL Server Authentication all correct

I have even gone into the local PC where the SQL is located, i can connect without any issues and I have reset the password for the profile which is Admin

I am using server type: Database engine (I am putting in here the IP address and I have checked and it is still correct)

Server Name: IP address

Authentication: SQL Server Authentication

Please help
