V1.4.1 : GnuTLS error -110 in gnutls_record_recv

#1 Post by tchicken » 2022-06-21 15:10

Hello everybody,

If I use an internal filezilla client, everything works fine, but if I work with another external IP, I get the error below :

Do you have an idea of ​​the problem ?
Is my security configuration sufficient ?

Thanks in advance for your help, Tchicken.

You configured FileZilla client to use the active mode, which means the server will try to connect to the address of the client. Can the server actually do that? Probably not.

In that case, you ought to use the passive mode and specify in the PASV settings of the server the host the server should respond with, which in our case is probably going to be the same as the one you had the let's encrypt certificate generated for.
