Facing problem in connectivity with primary hub from secondary hub via tunnel for new install of secondary hub
Tunnel Port is open as per UIM firewall documentation
Telnet is working from secondary hub to primary hub on tunnel port
Release : 20.3/ 20.4
Component : UIM - HUB
The remote hub connected via tunnel to Primary hub which has a NAT Ip listening on port 443
Wildcard tunnel certificate used for tunnel
Can see errors as below
hub: (ssl_server_wait_handshake) - SSL_accept error from host=xxx.xxx.xxx.xxx d=4000, err=-1, ssl_err=5(System Call Failure. Check errno.), errno=0(The operation completed successfully.
Root cause was that the domain name specified on the new secondary hub was not matching
The Nimsoft domain name which is specified during the secondary hub install is case sensitive
Example on Primary hub
<hub>
domain = SUPERGROUP
hubname = xxx
and Secondary hub was as below for which the case does not match the domain name case existing on Primary hub
<hub>
domain = Supergroup
hubname = xxx
Uninstall and reinstall the Nimbus infrastructure on Remote hub with correct case sensitivity for domain name and reconfigure the tunnel certificates
After this the hub tunnel was established successfully
