Description:

I am the IT for Essilor and a user downloaded and installed your program.
When it is finished installing it ask to launch. We say yes and it gets in.
However, if we close that window and go to our list and launch it it gives
us the 127.0.0.1 error code. Is there a bug in your system?
"pgAdmin 4 v3.3 (released Sept. 6, 2018)" is the version she downloaded and
installed.
