I can not load dll file on vps machine
If it is about dll on MQL5 VPS (and if you are talking about MQL5 VPS) so any dll is prohibited on this type of VPS.
According to the rules here:
No DLLs are allowed on a Virtual terminal. There is no physical capacity to use DLLs there.
If a program launched on a Virtual terminal tries to call a function from any DLL, this EX4/EX5 program is immediately stopped due to a critical error. Any DLL calls are forbidden.

Well ... what to do?
There is no refund for this MQL5 VPS (in case you already paid for that).
But I found some option related to it:

If you cancel a paid subscription, the remaining time is returned to your MQL5.com account in the form of "free" minutes. Which later can be spent on a new subscription "for minutes."The Virtual Server I'm using is not MQL5 VPS. It's my own server from Google cloud. It doesn't have any restrictions.
- Have you checked the rights to access files from elsewhere on your vps?
- Can you access (by a test script) this dll or other library files in that library?
- One terminal ist started in portable mode but not the other - correct?
Solved It.
I found out MQLMySQL.dll had no problem at all, the problem was on libmysql.dll. The libmysql.dll was not compatible with OS. So I downloaded a latest version and everything worked as it should. So remember to have compatible versions and sometime error messages can be misleading.

I have a weird problem, I have dll import line on my local computer working fine, but the when I setup the same dll on the VPS windows machine the I'm getting "cannot call 'ReadIni', 'MQLMySQL' is not loaded. I have installed the libraries in the
C:\Users\user_name\AppData\Roaming\MetaQuotes\Terminal\INSTALLATIONHASH\MQL5\Libraries directory.
Code
#import "MQLMySQL.dll"
weirdly it's working on my local pc with directory
C:\Program Files\MetaTrader 5\MQL5\Libraries
Local pc: Windows 10 x64
VPS: Windows server 2019 x64
dll: MQLMySQL.dll
The error message on vps: 2022.06.23 15:41:59.070 MYSQLINTER (AUDNZDb,M5) Cannot load 'C:\Users\vpsuser\AppData\Roaming\MetaQuotes\Terminal\6FDE27AB8905AD69A01A421FFD46289B\MQL5\Libraries\MQLMySQL.dll' [126]
