I'm trying to update my masternode following the guide at atlassian. The problem beginns at Install sentinel agent on masternode on step 7: at this point, running venv/bin/python bin/sentinel.py should return nothing but silence. This is how you know it's working. Instead I get: Invalid Masternode Status, cannot continue. "dash-cli masternode debug" also indicates a problem: Not capable masternode: Invalid protocol version This is my version: "version": 120100, "protocolversion": 70206, Anyone know what the problem might be? Tips & Tricks?
