UI in new builds inaccessible/can't login

Closed this issue 3 years ago · 1 comments

All, I'm relatively new to the FTS configuration (have been working with the GOV version of TAK server for a while), and have been running into issues using the current version of the UI (1.8.1) in any new installations (Windows, Ubuntu, Debian) in either a VM instance or directly on physical machine (the Docker version works very well; however, it is based on FTS 1.7.5 which does not support the video features that my organization needs). I continue to encounter issues with the UI installation, which I will try to summarize (the documentation online is fragmented, which is understandable for such a project, and seems based on 1.7.5 FTS and 1.5.1 UI).

WTforms does not seem to be properly called in the UI, which prevented the service from ever starting properly when calling run.py. (this was corrected by replacing all instanced of "TextField" in /usr/local/lib/python3.8/dist-packages/FreeTAKServer-UI/app/base/forms.py with "StringField").
After correcting the above and playing with the IP address fields in config.py and MainConfig.py, I was able to get the UI to start and display a login page. For the life of me, I can not figure if there is a valid user already created, or if there is a missed configuration item somewhere. Any attempt to login results in the following error:

I am supporting a disaster response exercise in a few weeks and would like to have version 1.9.1.5 functional so that we can use the much-needed video streaming feature. Your insight and assistance would be appreciated.

So, after moving a VM instance of the new installation to a different network, I'm able to login to the FTS UI. I haven't been able to determine what may have changed to allow this. I will continue digging through logs and close if no further issues (although the WTforms issue - noticed on Ubuntu 20.04 - may be worth discussing).
