New install Invalid Credentials/Connection Refused


(Supaiku) #1

I just installed Graylog on my Ubuntu 16.04.2 LTS Digital Ocean droplet and everything went somewhat smooth, except I get an invalid credentials error. Funny thing is, logs just say Connection Refused.

I did open up a bunch of ports in ufw, which helped:

(snipped a few from above)

I used this walk through:


It is for the wrong version of ubuntu, but didn’t see any apparent issues during process.
