The service does support multiple simultaneous logins.
I tried adding assertions to the Login, and verified that a correct response (a valid session id is returned).
I also tried running a loadtest with just 1 thread (which means that just 1 virtual user is used, right?), and get the same error.
Adding delays around the script, thinking that the problem was that the script didn't have time to execute, didn't help either.
- Login
- Delay 500
- Decrypt-script (which fails)
I'll keep digging on my end, and will get back to you if I have more info, thanks for your help so far
