Not synced, retrying fallback headers

[Stadicus]

I try to set up a sPRUNED node in a DigitalOceans droplet (Ubuntu 16.04.4 x64) and the installation went smoothly. Once I start the application, however, it does not seem to find the network.

I have a firewall set up, but only blocking incoming transactions. Outgoing, everything is open. Are there any network settings I need to configure. Or is it something completely different?

Thanks in advance for your support!

Hello, testnet servers are unreliable, I always thought I should set up one or two.
If you have notice of reliable testnet electrum servers you can add your own by making a PR.

Thanks for all your work and your quick feedback. I really might think about running an Electrum testserver (I already run a mainnet) if I have some hardware lying around.

I switched to mainnet for the moment and everything's working as expected.
