Renewal wrong fetch url

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: lakre.gr

I ran this command: certbot renew

It produced this output:
Attempting to renew cert from /etc/letsencrypt/renewal/lakre.gr.conf produced an unexpected error: Failed authorization procedure. lakre.gr (http-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching https://www.lakre.gr.well-known/acme-challenge/E3DbswC1o5YdykQvQX3VDj19iKQjQHbCCq2nuX27gII: Error getting validation data, www.lakre.gr (http-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching https://www.lakre.gr.well-known/acme-challenge/hg8Iqvlbzc34mjIeQ3NC6DBq27dWyFTtefooosuYiyY: Error getting validation data. Skipping.
My web server is (include version):

The operating system my web server runs on is (include version): Debian 8

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): IPSConfig 3

I am trying to renew domain www.lakre.gr. It is supposed to create a fetch url https://www.lakre.gr/.well-known/… but instead it creates https://www.lakre.gr.well-known/…
what should I do ?

Hi @christoforos,

This problem is caused by a mistake in a redirection in your web server configuration: it’s missing a trailing slash. It needs to redirect http://www.lakre.gr/ to https://www.lakre.gr/, but instead redirects it to http://www.lakre.gr (without the slash at the end). If you add the slash wherever the redirection is defined, it should work fine.
