Bug Description
I have a customer support bot on WhatsApp built with n8n (Cloud).
Between Friday afternoon and Monday afternoon, the bot stopped responding to my customers. Checking the logs from my WhatsApp provider, I noticed that the workflow webhook in the n8n started responding with a 404 error.
At first, I thought that the workflow might have been disabled for some reason. However, today (Tuesday), another workflow that runs via cron (schedule) did not execute, even though it is active.
This indicates that the issue is likely with the n8n Cloud platform itself.
When I tried to check the execution logs of the workflows to better understand the problem, I noticed something strange: all the logs for my cron-based workflow had disappeared.
In addition, for the webhook-triggered workflow, the logs are incomplete. For today (June 17), I can only view logs up until 14:39.
To Reproduce
I couldn't reproduce the issue.
Expected behavior
It should work correctly; it’s n8n’s own Cloud environment.
Operating System
Cloud
n8n Version
1.92.2
Node.js Version
I don’t know.
Database
SQLite (default)
Execution mode
main (default)

Apologies but this looks like an issue with the application level code. Due to volume, we can only answer platform level issues.
I've made this thread public so that the community might be able to help with you query.

Hello :-)
What do you mean? I don't understand, "application level code".
Regardless, looking at the logs, it's giving an error when accessing postgres, which I don't even have access to. It seems to me to be something from the N8N core.
Look, I'd like some support on this, since I'm not a CLOUD admin.
My N8N is unstable. Its infrastructure is managed by Railsway. Is there anyone at Railsway who can give me support? If not, I'll migrate my flow to another cloud and solve the problem.
I'll summarize the problem in other words here in case it wasn't clear:
1 - Over the weekend, my webhooks returned 404. Is there any way I can see what happened?
2 - The cloud execution logs simply disappeared. See the print above.
Can any Railsway employee help me here?
Thanks, everyone. Good morning.
