SUMMARY STEPS TO REPRODUCE 1. Add account 2. Choose Nextcloud from the menu 3. Enter server information with the port number (e.g. https://nextcloudserver.com:8080) OBSERVED RESULT Client connects to https://nextcloudserver.com:8080, the authentication takes places as expected. Client prompts what to synchronize (Contacts and/or Storage) but then fails reporting that the certificate of server doesn't match the site. There is another server at https://nextcloudserver.com (port 80/443) and the client shows its certificate at this stage instead of the one at port 8080. The synchronization fails before it starts. EXPECTED RESULT Client continues to respect the port number during synchronization.
