Trying to log into my FW, and keep getting this message 

[reaper]

try accessing the debug console https://<yourFWaddress>/debug and clearing the preferences:

additionally you could try updating all content (AppsThreats, WildFire, AV) from CLI

> request wildfire upgrade install version latest
> request content upgrade install version latest
> request anti-virus upgrade install version latest

also verify if you disk isn't full and if needed free up some space:

> show system disk-space 

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3             3.8G  2.5G  1.1G  70% /

Thank you for the tips! The Debug did not work though

Did you ever find a solution?  I'm having this same issue.

Hello Nrobison,

It can be related to a corrupted package (AV/WF).

If you are using Threat Prevention and/or WF license, please download and install again the latest packages:

> request anti-virus upgrade download latest
> request anti-virus upgrade install version latest

> request wildfire upgrade download latest
> request wildfire upgrade install version latest

If it still failed, try to restart the mgt server and the web server:

debug software restart process management-server
debug software restart process web-server

If it still failed, please open a ticket.

I faced the same problem on PA-3050 with PAN-OS 7.1.13 and resolved it by running:

> request wildfire downgrade install previous

Probably the wildfire update messed up something.

I ran into this same issue on a 3020 running 8.0.7.

I ended up running the commands in the following sequence as suggested in other users posts in this thread. 

> request anti-virus upgrade download latest 
> request anti-virus upgrade install version latest

> request wildfire downgrade install previous.

> request wildfire upgrade download latest 
> request wildfire upgrade install version latest

It's realy work, thx

[Jeff-Behm]

this one did the trick for me.

PA-500 on V7.1.7 (several dozen other 500's on V7.1.7 do not have the issue)

request wildfire downgrade install previous

After that completed, was able to log in via the webUI and Panorama reconnected
