Time delay on TTN-gateway receive messages?

Hi,
I just looked at the data i am receiving from a node on my desk and see a big time-delay in delivery between other gateways in my vincinity and my TTN-gateway… messing up my messages… receiving them twice…
ttn1

it looks like the backend is delaying them??
ttn2

anyone seen this before??

I also hada time delay on TTN GW, but a little bit different
My RPI Imst Recieved Message Instantly but TTN GW 1 to 3 Minutes later
All of a Sudden the delay was gone
A little bit later on anoter location everything fine Again, and all of a sudden the messages from the GW were delivered also minutes later…

It helps to know which packet forwarders you are using on the gateways (apart form the TTN GW as we know that one).

but it was only the TTN GW that had the problem…
The other GW’s are not the issue.

By the way… everything is working fine again… seems the TTN-backend has synced up again.

What packet forwarder are the others running? Packet forwarders using semtech protocol?

the other one (in the picture in my post) is not mine but i know its a kerlink.

That means the difference is Semtech vs ttn-gateway-connector protocol with the later suffering from the delay.
