I am in the home network, I deployed the ONLYOFFICE service by installing CentOS on a Hyper-V virtual machine in Windows 11 system (the virtual switch is configured as an external network, coexisting with other network devices at home under one gateway). I used Docker for deployment and specified the port as 8888. After deployment, I can access the service from the Internet through DDNS + port number 8888 configured on the router. However, the link attached to the activation email sent by ONLYOFFICE’s mail service does not include :8888, only the domain name address, which causes the link in the email to not enter ONLYOFFIC’s portal page correctly.
If the address of the current login page is accompanied by a port number (for example, toma.ddns.net:8888) when sending an email, please automatically add the port number to the attached link so that the link can be accessed normally.
