NetXMS Support Forum

I tried to install NetXMS latest version  4.4.1 on Windows 10 with MySQL80 several times, and every time it cannot connect to the database server, no matter what username/password combination I used (tried also to change authentication method to legacy password). In addition to that, I cannot login to the NetXMS server for the first time, no matter what client I use - new webUI, jar or legacy web, I always get message "Connection refused"...
I thought it is just run-and-use operation, but for me it's mission impossible... Where'm I wrong???

Yes, the MySQL client library shipped with NetXMS requires to use "legacy password" mode (it's possible to replace this lib, but it's not what we are currently fixing).

I've just tried installing mysql-installer-community-8.0.34.0.msi and netxms 4.4.1, it worked fine.

Did you check "Create database and database user..." on the attached screen during installation:

Yes, of course, every time, I even manualy made netxms_db schema from NetXMS mysql template, but the problem is with rights, NetXMS cannot login to MySQL for some reason... I can't figure it out why...
Today I tried to install on Windows Server 2019, and got totally the same result...

Here is the part of a log file:

First thing to try would be 127.0.0.1 instead of localhost - may be localhost is resolved into ipv6 address and database does not like it?
