Tls port stuck active

Slb-ext tls port seams to be stuck active high . Has been working well prior several months . Tried updating gsender from 1.5.3 to 1.5.6 with the same results.

I can press the tool setter but the active status ( green light ) in gsender just stays on never turning red . Unplugging the phoenix connector from the Slb -ext controller still shows green status light never changes to red light. any ideas on a fix ?https://www.facebook.com/share/v/17dRrwGKfQ/?
