REALTIME channel CHANNEL_ERROR after a few hours in supabase.com #1414
Description
Bug report
- I confirm this is a bug with Supabase, not with my own application.
- I confirm I have searched the Docs, GitHub Discussions, and Discord.
Describe the bug
My code is running in node not in background, idle, etc.... After a few hours the client disconnects and DOES ALMOST NOTHING to reconnect.
I have tried to remove all the channels, unregister... NONE of that seems to work.
Trust in Supabase
this.channel = this.supabase.channel('schema-db-changes')
.on('postgres_changes',
{
event: '*',
schema: 'public',
table: DEPLOYMENTS_TABLE
},
(payload) => {
this.emit('deploymentChange', payload);
}
).subscribe((status, err) => {
Logger.info('Supabase deployments channel status:', status);
});
}After a few hours

daemon-1 | 2025-06-06T04:05:53.636571958Z Supabase deployments channel status: CHANNEL_ERRORTry to recover
so I tried to remove the channel and try to register again
.subscribe((status, err) => {
Logger.info('Supabase deployments channel status:', status);
if (status === 'CHANNEL_ERROR') {
Logger.error('CHANNEL_ERROR:', JSON.stringify(err));
this.supabase.removeChannel(this.channel);
this.setupRealtimeListener();
}
});the result
daemon-1 | 2025-06-06T12:49:04.521578951Z Supabase deployments channel status: CHANNEL_ERROR
daemon-1 | 2025-06-06T12:49:04.521849659Z CHANNEL_ERROR: undefined
daemon-1 | 2025-06-06T12:49:04.522545547Z Supabase deployments channel status: CLOSED
daemon-1 | 2025-06-06T12:49:14.524323649Z Supabase deployments channel status: TIMED_OUTCHANNEL_ERROR undefined 🤦
Here deleting the channel and try to reconnect ends with CLOSED channel
