Issue with Filezilla

Yes, that's exactly what I put, I get so frustrated with this software that I get mixed up. Sorry.

It's been a while since it stopped working, whereas before I had no issues.
I also tried it on a friend's site for which I had built a website with his details: no problem before, and now the same issue, I can't connect with Filezilla. I wondered if it was due to my PC, but no, because on other people's PCs, it doesn't work either.
I had no issues before.

Which version of Windows, which version of Filezilla, and what firewall/antivirus?

--

Thank you very much for responding to me.

So,
Version: Windows 10
Antivirus: Avast free so, no firewall or the Windows one I think.
Filezilla: version 3.37.1.0

I just tried again, I'm doing a copy/paste.
Connection attempt failed with "EAI_NONAME - No node name or server name provided, or unknown".
Error: Unable to establish a connection to the server
Status: Waiting before retry...
Status: Resolving address of ftp-perso.orange.fr
Status: Connection attempt failed with "EAI_NONAME - No node name or server name provided, or unknown".
Error: Unable to establish a connection to the server

Have a good day and thank you.

Version : Windows 10 Home? Pro? 32 or 64 bits? Up to date? (1803 (17134.320))

Antivirus : Free Avast so, no firewall or the one from Windows I think. Uninstall this crap https://www.avast.com/fr-fr/uninstall-utility

Filezilla : version 3.37.1.0 32 or 64 bits?

Windows 10 Home up to date,
Filezilla 64-bit

Okay, for the uninstallation of Avast, but what should I put in its place?
I only have Windows Defender and from what I've seen, it's not very effective.

I’m willing to remove Avast, but I’ve had it for a long time and before Filezilla started giving me trouble, it was working perfectly.
I’ll uninstall it and try connecting to Filezilla, we’ll see!

I uninstalled Avas, I tried again and it still doesn't work.

I'm sorry, it's still not working.
I've tried Anonymous, Normal, Interactive, it's always at the password level that it gets stuck.
It doesn't recognize me.
By the way, in the dropdown window, that's what it tells me.

Thank you for your patience.

It's totally crazy! When I type http://perso-ftp.orange, the page says the connection failed. I've tried several times. The same goes for www.cijoint.com. Both http:// are systematically erased.

I should mention that we moved with a new email address (change of department), after a problem with Orange, the repairman made sure we could use our old email address which we still use. He tinkered quite a bit.

But now, I've tried with the address that is the main one, so the last one, and it still doesn't work.

Ultimately, I think the problem comes from the mix-up.

I don't know what we can do. If we can't fix it, too bad, you will have raised a problem that I had completely overlooked.

Thank you for your patience.

Hello, I realized that it's Malware Premium that was blocking the attached site, I've removed it, here are the screenshots:

and

When we change departments, we also change our phone number, since the email address is linked to the Box, there you go!

Yes, we have canceled the contract for our old region. As I explained to you, normally our email address is the one that is written, but the Orange technician arranged for us to use both addresses. So, we mostly use the old one.

I believe the problem comes from that.
