Header fields are too long for server to interpret

[korry]

I had the same problem - I closed the browser tab I had been using, opened a new tab, and browsed to 192.168.4.1 and problem solved. Hope that helps.

having exactly the same issue however my PW is only 20 ASCII characters.
When I connect to the new AP i get the following logging on the UART console:

W (16264) httpd_parse: parse_block: request URI/header too long
W (16264) httpd_txrx: httpd_resp_send_err: 431 Request Header Fields Too Large - Header fields are too long for server to interpret.

Any idea what can be wrong.closing the browser does not work for me

Does ist help to increase HTTPD_MAX_REQ_HDR_LEN in the configuration?

[lecrams]

I changed HTTPD_MAX_REQ_HDR_LEN to 1024 rebuild the project and now it is working.
Thx for the fast support

I am facing similar problem as related to uplink Wifi password, that is 63 char long, it just is not saved, will try suggested HTTPD_MAX_REQ_HDR_LEN fix.

Another thing I noticed that there might be some issues with special characters, "+" gets replaced with space(" ").
Tried with set_sta and from webpage, both seem to do so.
