switch wont accept multiple vlans from cisco

Hello!
A short description, from a cisco 2960 i've tried created a trunk carrying 3 vlans(200/500/600) and vlan 1 as native.
For starters i configured the tp-link to include all ports on all vlans as untagged just to get it upp and running but a soon as i activated the trunk on the cisco the tp wont connect anymore. It indicates that it is connected but neither the switch ip or any devices connected to it are reachable.
After that i went into troubleshooting, firstly just enabling the port on the cisco as a normal vlan-port cycling through the vlans and in that case the tp connected.
Made sure dot1q encapsulation was active and as the cisco only is able to use the dot1q i also ruled that out.
The next thing i did was to only allow VLAN 1 on the trunk and use that as a native and the tp connects fine.
So status at this point is, port connected to the tp on the cisco is configured as trunk, VLAN 1 is the only one allows and is native.
Now i tried to allow another vlan(200) on the trunk and the tp immediately takes a dive and wont connect, if i remove 200 from allowed the connection goes back up again.
Also tried only allowing another VLAN ie 200 and setting that as native on the cisco but the tp doesnt connect in that case either.
Any help in this matter are appreciated as im somewhat stuck.
I hate to hijack threads but can you elaborate this a bit ?
I create VLAN 10 and 20 on my Sophos XG
The Sophos XG is connected over a LAG to the TP-Link Switch and from the TP-LINK i want to connect
a other switch - is a cisco sg-350 - i cant get the tp-link to pass trough the vlans to the cisco
The Cisco ports are configured as trunk ports - but how can i configure the tp-link right with the new gui ?
when i provisioning an VLAN to an Device on the tp-link is everything clear
here are an example of an Port Config for an specific device
i setup the port 21 as untagged an as tagged port i select the trunk to the sophos xg firewall
as PVID i set PVID 10 for the Port 21
Here is no Problem the vlan provisioning works , but how the TP-LINK trunks the VLANS to the Cisco Switch
On the new Gui there is no Trunk-Mode anymore (on old gui there was the trunk mode for port config)
the cisco switch can also used general trunk mode (i´ll tried that too , but so far I am not able to reach VLANS via the
TP-LINK on the Cisco switch
(I have of course set up the VLANS on the Cisco)
