Hello,

For the past few days, I have been getting the following error message when accessing my private cloud:

Service Unavailable (503)
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

The problem disappears and reappears on its own for no apparent reason. As I write to you, I have access to my cloud (but for how long?).

On the other hand, I have a synchronization problem with the Android application Joplin (free equivalent of Evernote) which gives me the following error:

Error. Please verify that the URL, name, password, and so on are correct and that the destination is reachable. The reported error is:
PROPFIND : Unknown error 2 (503): <IDOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>503 Service Unavailable</title>
</head><body>
<h1>Service Unavailable</h1>
<p>The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.</p>
<hr>
<address>Apache/2.4.38 (Debian) Server at xxxxxx.xxxxxx.xx Port 80</address>
</body></html>
(Code 503)

What’s odd is that Joplin continues to sync perfectly from the desktop apps on both of my laptops but not on my phone.

I think this problem is caused by the following error message that I find in the Logging part of the Nextcloud administration interface:
[index] Error: The requested uri(/api/all_etat_1.6.sh) cannot be processed by the script '/xxxxxx-xxxxx-xxxxxx/index.php')
0. /var/www2/nextcloud/lib/base.php - line 953: OC\AppFramework\Http\Request->getRawPathInfo()
1. /var/www2/nextcloud/index.php - line 36: OC::handleRequest()

This problem is beyond my technical skills and my research did not lead me to a solution. That’s why I come to you to find out if you can tell me where my problem comes from and how to solve it?

Thank you in advance.

You have no idea?
