  The SAP error message /PM0/ABB_INTERFACE626 PFO: Problem connecting to remote system typically indicates that there is an issue with the connection between your SAP system and a remote system, which could be another SAP system or a non-SAP system. This error can arise due to various reasons, including network issues, configuration problems, or authentication failures.
  Causes:
  
  Network Issues: There may be network connectivity problems between the SAP system and the remote system. This could be due to firewalls, routing issues, or network outages.
