Team's Discord channel is very active, I posted and got a useful response very shortly.

This coin is well supported. Many teams have moved support to Discord or Telegram as its much easier then this forum.

Solution was to simply add more nodes to the conf file inside the sequence wallet data directory (during installation it asked you for location, default is probably your windows C:\Users\\AppData\Roaming OR C:\ProgramData folder)

I added the following, restarted the wallet and viola, made a number of connections and started syncing.

addnode=81.221.130.197
addnode=81.221.131.172
addnode=81.141.2.125
addnode=5.80.235.102
addnode=108.61.170.242
addnode=92.9.101.96
addnode=45.77.77.109
addnode=81.221.70.211
addnode=100.45.73.75
addnode=81.221.130.199

As pointed out above, additional nodes can be found here:
