Connection bug 096.7

[Damien]

After some hard work fixing the problem to make people connect to my server another problem appears, this time when some people logon to my server they directly get stuck at 'Verifying Account' and the pol console
show errors like these:

Client connected from 81.233.115.16 (2 connections)

These errors appear when i tried to logon, i tried to accounts, but also when my friend tried to logon. The strange thing is that the first time i succeed to login and play normally but my friend got this error, so i restarted POL. Afterwards I got the error but my friend could login.

My question is; what create these errors and how to fix it?
Im using POL 096.7

Thanks for all replies!

is Your client riced (uorice or razor)???

this look as a client crypting problem

[Damien]

Greetings coltain!

Im using client 2.0.0 with UOAssist, thought i tried connecting with
and without UOAssist and no success.
I also tried to change:
ClientEncryptionVersion=2.0.0
to
ClientEncryptionVersion=none

But yet no success, thanks for the reply!

Did a test with a No_Crypt_Client.exe and yet the same error appear.

[coltain]

I don`t use uo assist so..

I checked This packets and:
Packet 0xA1
Packet Name: Update Current Health

Packet Build:
BYTE[1] cmd
BYTE[4] playerID
BYTE[2] maxHealth
BYTE[2] currentHealth

Packet 0xD1
Packet Name: Logout Status

Packet Build:
BYTE[1] cmd
BYTE[1] unknown // always 1

Did You checked another client?? 5.0.6.5 for eg.. I think 2.0.0 is old sa some packets may be... read wrong

Strange enough without doing any changes at all, it works now.
Thanks for all help tho!
