What did you do?

although there is no error message code in the codes to write to the screen, it gives this error

2020/09/15 19:35:22 Unsolicited response received on idle HTTP channel starting with "\r\n"; err=
2020/09/15 19:35:24 Unsolicited response received on idle HTTP channel starting with "\r\n"; err=

the software works, but it constantly prints this error

What did you expect to see?

What did you see instead?

Could you provide an example of the code that produced the error, preferably as a Go playground link?

[antichown]

it is difficult to find which one gives the problem because the site address from txt is too much, but I saw that it gives it on this site by debugging.

as you can see, the error message gives an nil answer, but it gives an error
