Have started a new post with the correct title.
I have a problem when trying to use smartlink from Gibraltar to the UK the waterfall and spectrum do not display.
Have done some further testing and the connection is fine when I use within the UK 3/4G and Wi-Fi/Ethernet on WAN. So getting out through router fine.
However trying to setup in Gibraltar with my son and the non display of waterfall and spectrum persists. The audio appears OK
Following tests have been completed and all showed the same problem.
1 - Tested two separate high speed fibre lines (and routers) into his house in Gib
2 - Two separate PC's (Desktop and MacBook running Win10). The desktop we had used before running SSDR via a VPN.
3 - 4G connection into Gib and across into Spain
4 - On his works network with laptop and works PC (extremely high download speed and behind no filters)
These tests smartlink worked OK.
5 - Tested the laptop from Croatia on Hotel Wifi and it was OK
6 - He did a VPN from Gibraltar home to DigitalOcean in London and smartlink worked ok. (but too slow for practical use)
It appears that this is something that affects the Gibraltar / Local Spanish area.
Anybody else had a similar experience.
Shall I raise a help ticket?
