[UPDATE] when setting EXTERNAL_IP in config/webapp.config.local.json, like this:

{
  "apiEndpoint": "http://EXTERNAL_IP:4000",
  "googleAnalyticsId": "GOOGLE-ANALYTICS-ID",
  "identityResolverEnabled": true
}

I get some data on the explorer ui. But still having data update issue on tne navigator console

fetchHelper.ts:41          GET http://88.99.32.163:4000/currencies 400 (Bad Request)

websocket.js:138 WebSocket connection to 'ws://88.99.32.163:4000/socket.io/?EIO=4&transport=websocket' failed: WebSocket is closed before the connection is established.

No firewall or network restriction on the server, neither docker settings.

Thank you in advance.

Can you try and change this line https://github.com/iotaledger/one-click-tangle/blob/9210fada7fb4cfcf5e846f9fd83cc7b7189d9398/explorer/tangle-explorer.sh#L80

change it from localhost to an ip where the explorer api is located, even if it's on the same server, also the port and see if it works
