Synology says “The operation failed. Please log in to DSM again and retry”

As the title states, this is my error. I already have a renewing certificate for my main domain, I migrated two websites, was receiving this error but still after some time the certificate magically popup. However, with the fourth domain, the certificate does not popup and I am still receiving this error message.

I do have 80/443 accessible. I do have webstation installed and properly configured. I am not sure whether I also need DNS server properly configured but I did some stuff there that seems to me to be correct as I am mirroring my first domain.

My domain is: (working long time, cannot renew), (received after magic popup with the error message), (dtto - the same as previous), (cannot get certificate)

I am using synology nas DSM interface.

It produced this output: “The operation failed. Please log in to DSM again and retry”

My web server is (include version): Apache 2.2

I can login to a root shell on my machine (yes)

Hi @vahaldor

I don't understand your question. There is a new certificate, created today.


There is the same, a new LE-certificate.

Yes, it finally popped up for as well. But I still get that error message at the end of every processing cycle

Hi Jurgen,
sorry for this confusion but I realized that I have similar problem elsewhere that might explain this weird behavior. When I want to install a plugin in wordpress, it returns 504 gateway timeout on Appache server 2.4. When I keep the computer away for some time and restrain from touching the browser, the plugin is installed and I can realize it by refreshing the website. This same behavior I experienced with getting the certificates.

It looks like some default timeout of the server that returns an error while the process continues on background and it continue if I do not interfere.
