**Versions:** NextCloud from the Hansson IT image Ubuntu 20.04 NextCloud 20.05 NextCloud Mail 1.8.0 ProtonMail Bridge 1.5.4 Apache 2.4.41 PHP version 7.4.3-4 **The issue you are facing:** Mail, using ProtonMail Bridge can load list of messages by box, can load message subject in preview pane, but cannot load body of email message. Any help offered is greatly appreciated. **Is this the first time you’ve seen this error? :** Y **Steps to replicate it:** Proton Mail Bridge is configured to successfully connect to supported account type (two factor removed just in case). NextCloud User’s Mail settings under [Manual] ```auto IMAP Host : 127.0.0.1 IMAP Security : StartTLS IMAP Port : 1143 Username / Password verified against Bridge config SMTP Host : 127.0.0.1 SMTP Security : StartTLS SMTP Port : 1025 Username / Password verfied against Bridge config ``` 1. Save config. 2. Click on InBox. 3. UI shows list of emails, along with icons to the left. 4. Select a message from the list, UI shows Message Subject in the preview pane, nothing more. 5. Click the subject in the preview pane to expand the message to view the Body, the spinning circle starts and never ends. **NextCloud Log** ```auto Error mail OCA\Mail\Exception\ServiceException: Could not load message /var/www/nextcloud/apps/mail/lib/Controller/MessagesController.php -

I’ve gathered some more information. Deeper log entries around a test session. It would appear that NextCloud is trying to interact with something at 192.168.0.1, which is a UBNT Secure Gateway and I dont think its going to respond with anything interesting to NextCloud Mail. NextCloud server is at 192.168.0.8 and it should be addressing the bridge at 127.0.0.1, not 192.168.0.1. I’ve looked again at the config.php and did not see an ip address other than the loopback. Log from jq conversion of the NextCloud log follows: ```auto { "reqId": "gf9AOkqQnGcpnS1yLOax", "level": 3, "time": "2021-01-24T09:39:56-06:00", "remoteAddr": "192.168.0.1", "user": "[USERNAME
