please use a front end that allows you to switch nodes.
Beeswap auto switches and lets you see the nodes. Hive-engine has not been 'broken' in months. We are working on an issue, possibly an intentional attack, but certain nodes (especially the 'main' node) goes down, does not mean the network is down.
Look here:
https://beeswap.dcity.io/swap has token markets now too.
Tribaldex can switch node in settings, but you will have to guess which one is working (or use beeswap to see which one is working and select one of those in tribaldex settings).
Love you 😍
