Please make sure to regularly check your Galvan account to ensure your Node is online and running properly.
If your Galvan Node(s) go offline and you use Block Fabric press on the 3 dots to the right of your Block Fabric server and choose Restart Server. After about 30 minutes, your Galvan dashboard will be updated and you can view the node status.
If that does not bring your Galvan Nodes back online try to destroy and reset up your instances. If you need instructions to set them up again feel free to look at the FAQ here.
If restarting, deleting, and starting new servers does not get your nodes back online, please check with the Block Fabric support team by emailing support@blockfabric.host for more help.
