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 using the FQDN or the 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 full ctxsta.dll path.
Example of the configuration that fails:
