Any suggestion for a quick fix or workaround would be appreciated.
I have a similar issue in TW and had the same in 15.1 and 2 Leap. I found that setting in /etc/nscd.conf the value enable-cache hosts no did help a lot. In my experience nscd.conf has an issue when refreshing the cache that causes a DNS failure for a certain time frame (if you wait, typically after e.g. 20 minutes or so, the things turn normal. Setting this value solved the problem for me. I am using unbound BTW. I did not have to set it in TW but recently the issue appeared so i will try also to set it in TW. (TW typically: cannot resolve address in Firefox etc, (no, I did not use the build in DNS resolution of FF) and when you try with tor or tor browser all works).
