What version of Workbench are you using ?
I know that there were an issue with Workbench 4.1 with no SP and the SSL websites.
Try to look at this :
I'm using Workbench 4.2... I have TMART 4.2 deployed already.
Btw.. this is the error message into the TrueLog Explorer and I try a weburl() call in my script.
WebUrl(3758556136 - unknown error code, SSL Connect)
Sorry, I can't help you on this one. I tried to record SSL one with wb 4.2, no issue on my side (even with the SSL warning screen).
