ProCall Client login error 'The server version is not compatible'"

Observation

When the Procall client logs on to the UCServer, "The version of the server is not compatible" is displayed, although the ProCall client and UCServer versions are identical.

Example screenshot: ProCall Client login fails - "The version of the server is not compatible"

Possible cause

The UCServer does not send a response to the asnNegotiateServerConnection request from the ProCall client.
The server version is normally transmitted to the ProCall client in the response.
The client compares - without having received a response from the server - its own version with the server version (which it does not actually know) and comes to the incorrect conclusion that the versions are incompatible.

Solution/Procedure

The UCServer performance and network infrastructure should be checked . If in doubt, open a ticket with estos Support and provide the following data:

• ProCall client debug logs Creating a debug log for ProCall client
• UCServer debug logs Creating a debug log for UCServer
• Memory image of the UCServer (created while the error behavior is being observed) Creating a dump file of UCServer
• PCAP recording via Wireshark Trace on the UCServer Create PCAP record file/trace for UCServer – network analysis
• Information on ProCall Client/UCServer IP addresses
