Supl sever not reachable, A-GPS setttings?

Evening,

I'm not 100% sure what settings I'm looking for so I will try my best to explain.

My phone is a Sonim XP5300.

I recently had the phone sent the phone to fonefix to have multiple software issues.

Anyway, whenever I open an application that requires the use of GPS it tells me, "SUPL sever not reachable"

This only happens when I have A-GPS turned on, when I have it off, it doesn't come up with this message.

I can still get a very accurate lock on my position, so gps is working, but I'm assuming that the assisted gps isn't working.

So in the AGPS settings on my phone, I have the follwing settings which can be adjusted, FoneFix already set them up, I will list what they wrote.

The settings are as follows,

Address: Live.Vodafone.Com (I tried changing the first letters to lowercase, it did nothing)

Data acount: VF WEB (i have three different accounts to choose from which are VF MMS, VF WAP, and VF WEB.

Port: 0

TLS: Off (has option of either on of off)

Any ideas, or help are appreciated.

Kind regards.

Travers.
