I was able to solve this problem for R2019a on a CENTOS7 (64bit/only) system.
In the first step i located the jxbrowser-chromium (MATLAB/R2019a/sys/jxbrowser-chromium/glnxa64/chromium)
I opened a terminal and entered>
ldd jxbrowser-chromium | grep -i found
which gave me
libcrypto.so.1.0.0 => not found
Luckily I had the idea to search if the file was already on my system. I do not want to risk downloading a library that does cryptography "obviously" .. somewhere on the internet.
that the missing file came already with the installation. I copied the file and send it to
and also set
in Matlab Command Window. Restart Matlab and it works. But, loading the pages is still pretty slow. This could be improved !
