InfluxDB 2.0 and TLS problem


My InfluxDB 2.0 beta 5 instance running without TLS, on Ubuntu 18.04, runs fine (using directly the IP address of the server as well as with a domain name).
However, trying to add TLS doesn’t work. I followed the procedure as described in


$ sudo openssl req -x509 -nodes -newkey rsa:2048 \
  -keyout /etc/ssl/influxdb-selfsigned.key \
  -out /etc/ssl/influxdb-selfsigned.crt \
  -days 9999

works, but gives at the beginning
Can’t load /home/ubuntu/.rnd into RNG
140100323504576:error:2406F079:random number generator:RAND_load_file:Cannot open file:…/crypto/rand/randfile.c:88:Filename=/home/ubuntu/.rnd

I don’t know if this influences the rest of the process?

I tried the same local on my Mac, where it runs fine, and copied the cert and key to my Ubuntu box.

Anyway, both result in that I can’t access my InfluxDB instance using TLS!

This site can’t be reached

Anyone an idea what can be the cause that I can’t access my influxDB instance using TLS?
