Hi Nastya_Khovrina ,
I am not using JDBC or Groovy script.
I agree with HimanshuTayal. I tried to same today morning for one of the request. I am unable to cancel. I do not see any error in the logs as well. See attached. I see error before. I am trying hit Auth API with NTLM. After I send request, I see always cancel (in attachment) with no error about the request status. When I click cancel, I see below error in the logs. I tried same in Postman and works fine. It seems like an issue with SOAPI UI Pro tool. I would suggest SOAP UI Pro should have timeout of the request without showing cancel button always. If we will proper error if the request is taking longer time, it should give proper error message. I am sure it is definely a SOAP UI Pro bug as same the URL works fine in Postman.
