We upgraded service desk server that uses apache tomcat to run. Tomcat version changed from 7.0.55 to 7.0.62 After upgrade 2 PRTG HTTP XML/REST Value sensors that monitor that server stopped working. They show "An unexpected error occurred on a send." instead of sensor value. Pade is returning some values in JSON forms, it did not change during upgrade. Same page that is used for sensors if perfectly forking in both ie and chrome. Other sensors, like HTTP Advanced and HTTP SSL Certificate Expiry are working ok too. Need help.
