Zimbra Drive extension connection test : Impossible to connect to Zimbra Drive extension (response http code: 400 )

Nextcloud version 12.0.3
Zimbra Drive NextCloud Version: 0.8.15
Operating system and version Centos 7
PHP version 7.0.25
SSL Let’s Encrypt : yes

Zimbra
Zimbra zcs-8.7.11_GA_1854
SSL Let’s Encrypt Yes

Is this the first time you’ve seen this error?: yes

Can you reliably replicate it? (If so, please outline steps):

the integration with zimbra and nextcloud.

when I do the test from nexcloud, the following error occurs:

[FAILED] Zimbra Drive extension connection test: Impossible to connect to Zimbra Drive extension (response http code: 400) URL: https: // midomain: 443 / service / extension / ZimbraDrive_ConnectivityTest VALUE: 2

and from the zimbra I have no problems the drive tab is visualized with the content that is in nextcloud,

but if I’m going to authenticate with a zimbra user in nextcloud, it does not enter.

The issue you are facing:

Doing the test from Nextcloud shows the following:

[OK] Zimbra Drive app installation test : Zimbra Drive app is installed.

[OK] Enabled Zimbra’s users test : Zimbra’s users are enabled.

[OK] Enabled Zimbra’s user login : Zimbra Drive authentication is enabled.

[OK] Is server url set test : The server url is set.

[OK] Is server port set test : The server port is set.

[OK] Zimbra host connection test : Zimbra Drive app can reach the host.

[OK] Zimbra authentication page connection test : Zimbra Drive app can reach Zimbra’s authentication page.

[FAILED] Zimbra Drive extension connection test : Impossible to connect to Zimbra Drive extension (response http code: 400 ) - URL: https:midomain:443/service/extension/ZimbraDrive_ConnectivityTest VALOR: 2
