Im  using websphere deploy plugins to execute the first task and all is working fine when i deploy on server 1 (Dev), but i when to want execute the second task for deployment to server 2 (SQA) this proccess fail to ssl certificate. I have checked and the certificate is in the keytool. 

After a lot of testing,  i restarted the Jenkins server and i executed the task to server 2 and after it finished i executed to  server 1,  now, the server 1 show the error but the task in server 2 works fine.

please help me with the soluction of this problem
