@eadistar The error should be seen when a non-upgradable HTTP request is made to the /_blipsync endpoint, which only accepts connections that can be upgraded to websockets.
What client are you using to connect to Sync Gateway? Is it Couchbase Lite? Or a web browser?
It may be that your Apache config is not allowing websocket upgrades to happen.
OK, in that case I'd double check that your Apache reverse proxy is configured for websockets.
These might be a good starting point:
Hi @bbrks Thanks for your response. I reconfigured apache to handle WS. This issue has been solved from my side.
I've filed an issue to improve this error message in the future:
