In the current build, STA server binding does not handle the explicit ctxsta.dll path correctly during configuration processing.
Applicability:
The STA server configuration fails when either of the following commands is used:
(1) bind vpn vserver <vserver name> -staServer https://<staserverfqdn/ip>/scripts/ctxsta.dll

[or]
(2) bind vpn global -staServer https://<staserverfqdn/ip>/scripts/ctxsta.dll

As a workaround, bind only the STA server FQDN or IP address without the /scripts/ctxsta.dll path.
Use the following format:
(1) bind vpn vserver <vserver name> -staServer https://<staserverfqdn/ip>

[or]
(2) bind vpn global -staServer https://<staserverfqdn/ip>

A known issue exists in the build 14.1-66.54 and 14.1-66.59 where STA server binding fails if the STA server is configured with the complete ctxsta.dll path.
Example:-
Configuration that fails: bind vpn vserver vpnvserver -staServer https://example.com/scripts/ctxsta.dll
Scope of Workaround:-
This workaround applies only when the intended STA endpoint is the default scripts/ctxsta.dll
