Permissions between Publisher and Subscriber
WORKAROUND:
1. Verify the SQLServer and SQLAgent logon account password. It may have changed and failed to connect.
2. Setup an alias with the correct port and connect via the alias.
3. Use a UDL connection test on the subscriber side to verify you can connect to the instance from your operating system.
