I noticed something strange, when I share a library and send the share-link via e-mail, I get the error message “Please check the network.” Despite the error message, the e-mail is sent and arrives at the recipient.
This error only occurs if I try to send the e-mail by clicking the “Share” button.
Sending the share link via the Share icon works fine.
The error occurs with several systems.
Seafile Professional Server 7.0.7 and Community 7.0.4, operating systems Ubuntu 16.04/18.04 and Debian. All logfiles are empty and shows no errors.
