Contextualizing... when trying to connect to the hosting server, by FTP, always returns the 220 status and, after a few seconds, disconnects by time
Being a status of type 2xx is not an error neither mine (4xx) nor on the server (5xx), but some problem has (since it does not connect), so what does this status mean?
While giving context to the question, a general answer is welcome

FTP is not HTTP, are different protocols, work with different tools, have different purposes.
There is no HTTP code 220, what exists in the range of 200 are:
The code specifically 220 is FTP, follows the description:
Service ready for new user.
Translation: Service ready for new user
This indicates that the server is ready for a user to connect and therefore receives such code, as the link http://www.serv-u.com/kb/1509/220-FTP-Reply-Code
When using the command REIN (command that restarts) that terminates the current user, the protocol can send the code 220, this command
REINITIALIZE (REIN)
This command Terminates a USER, Flushing all I/O and Account information, except to allow any transfer in Progress to be completed. All Parameters are reset to the default Settings and the control Connection is left open. This is identical to the state in which a user finds himself immediately after the control Connection is opened. A USER command may be expected to follow.
I didn’t know there was ftp status, I thought those values were universal, thanks
I edited the question, what do you think?

The question was edited correctly in revision number 3 and then reverted to the original for no apparent reason. I will base myself on the FTP protocol, since as already said, the 220 status does not exist in HTTP.
The 220 response means that the connection has been established (SYN) and the server is ready to receive credentials (if required). This status occurs after the 3 handshakes initials by port TCP 21 as shown below:
That is, the client sends a request SYN (to synchronize) to the server (1st step), the client responds with SYN-ACK (synchronize-took note, 2nd step) and the client returns an ACK (took note, 3rd step).
After the 3rd step the server sends the status 220 informing that the connection has been established and again the client sends the ACK (became aware) along with the credentials (user and password or only user if the server allows anonymous connection).
Regarding being disconnecting alone after a few seconds "by time", it may be N factors, since downtime or due to some configuration in the client.
Here are some reference links about FTP connections:
As I commented in the other answer, I didn’t know there was ftp status, I thought these values were universal. I edited the question by running tags and title. Regarding the "by time", I believe it is some configuration in Ilezilla itself not to keep the connection open for a long time, thanks for the answer
Have option there that you arrow downtime before disconnecting.

Searching high above, I found the following: 220 - Service ready for new user. In the hosting service in question there is nothing specific to this case?

@Tuxpilgrim thanks, if you have not found

What I said I found in wikipedia, but when it came to ftp errors, I was curious about your case :p

A very important comment: FTP is different from HTTP. They are different protocols and have different return codes.
– Woss
Do you want to know FTP or HTTP? In the title and tags speak HTTP and FTP text, which are different things
