Thank you for your help. The user email and password seem to be correct. I cleared them and reentered just to check and I am still getting the same result.
I get the following prior to the log I posted above. This seems to pertain to the cameras, but perhaps Im am wrong:
warntapo_device_install: [method:getDiscData, status:INVALID, respData:null, error:groovy.json.JsonException: expecting '}' or ',' but got current char '"' with an int value of 34
The current character read is '"' with an int value of 34
expecting '}' or ',' but got current char '"' with an int value of 34
line number 1
index number 1008
***It goes on to list some device specific information which seems to refer to the model numbers of the cameras.
