Mango runs but can't get login page to appear...
-
I've been running Mango for a couple years at this site. It's been very reliable. But when I tried to login today the login page never appeared - the browser timed out (even after several retries).
I've stopped/started it several times with no luck. However, I've found some suspicious startup messages. There are 12 identical messages like the one below. Any suggestions?
ERROR 2018-02-15 10:51:41,224 (com.serotonin.bacnet4j.transport.DefaultTransport.run:416) - Error during expire messages:

What version of Mango?
I wouldn't imagine that message would cause Mango to stop starting up / not start the web server. Can you please post your full log.

Hi mlavelle42,
Have you tried clearing your browser's cache and deleting the Mango/work/jsp directory?
The other thing to try would be launching Mango directly on a command line. Then if any errors escape to stderr you can share them with us. Navigate to Mango/bin on the command line and either
./ma.sh start
orma-start.bat
You may see resolution in that BACnet error if you updated, but I concur with Jared that is not the reason you cannot log in.

I deleted: mango/work/jsp and restarted Mango - but I was unable to login again. So I rebooted the processor to clear everything out. But Mango still wouldn't allow me to login (i.e. didn't get the Mango login page). Finally I shut Mango down and started it up again - to capture the startup messages - which are at this link.
It seems to startup OK until this message comes in: java.lang.NullPointerException.

Again, its highly unlikely that has anything to do with you not being able to login. I can see from the full log you posted that the web context is starting up. Are you sure you are connecting on the right port and any firewalls/proxies you may have in between are configured correctly?
