Ingame PING issue

[Ingame PING issue]

Could someone please help me????

 

Hello, since last Friday i have a huge issue with my Ping.

When i start to play, first 20 minutes is NO problem, but after time i have 'some' high pings as you can see in screenshot.
 

I tried much things to find the problem in my network but there was nothing wrong from my side.
I can play so many other games without any ping issues, like guildwars2 or blackdesert for example.

I also tryed to find a problem with pingplotter if i ping the EuroAion - Game Server IP 51.91.6.184 while playing, it does NOT show any problems or ping issues. Ping in plotter is between 20-40ms!
But ingame i have some higher than 150 or 200...

So the problem is just in EuroAion, no other game, JUST Ingame to see, no problem with my network and i cant find any solutions for the problem.
I deleted EuroAion, downloaded it again, same issue...
I moved it to an other Drive bcs maybe it is my HDD.. but same issue on my SSD aswell...
And curious is that everything else is working perfectly...

when i do a speedtest i get this result:

Download     260 Mbit/s
Upload     53 Mbit/s
Ping     6,4 ms

When i ping EuroAion Server i get this:

PING 51.91.6.184: 64 data bytes
--- 51.91.6.184 ping statistics ---
100 packets transmitted, 100 packets received, 0% packet loss round-trip
min/avg/max = 21.000/25.000/34.000 ms

 

So also no problem...
But as you can see, ingame i have high ping eeeevery few seconds...
i even tried to reset all my network settings but it has the same issue so i spent 2 hours to rebuild all my settings again on 2 router...
but the problem was still there...

i think the problem is somewhere else...
I also replaced my Router with a networkbride to the second router that i am just workin with one with less latency, but it is still the same issue
I called my provider and asked if they have any troubles atm, but from their side everything works and the connection from them to my router is just perfect...
i even bought a new networkcard but it is still same issue... thoght maybe the onboard card has a problem so i bought a new one
and of course i tried to deaktivate firewall and defender but it didnt change anything

I also changed this setting in regedit:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces...
TcpAckFrequency

when i use exitlag to get a perfect connection to the server, it shows me 18-26ms PING, but ingame it is still broker so it HAS to do something with the gameserver

and every way i can try to ping the conection between me and the server is no problem without any issues...

but when i am ingame i have the issue... if i ping the server, it doesnt ping like when i am ingame so the problem is the server


From Support i got that Link:

and this one

BOTH ARE NOT WORKIN IN MY CASE!

Could someone please help me????
