https: Failed to load resource: net::ERR_SSL_BAD_RECORD_MAC_ALERT . There is no problem when uploading some small pictures of several hundred kilos. Once it is greater than 3m, this error will be reported

but everything is fine under http.

when I see this error message, I think it should be ssl"s error, and then the domain name uses a [free DV version of SSL certificate], which indicates that the certificate is about to expire and reapplies for a new one, or the same error occurs.

the upload plug-in that was misused before was webuplaod,. I thought there was a problem with the plug-in, so it was replaced with the same problem as plupload,

ssl is configured as follows:

<VirtualHost *:443>
    DocumentRoot "D:\wamp\www\project"
    ServerName project.com
    SSLEngine on

    SSLCertificateFile "D:\wamp\bin\apache\apache2.4.9\conf\cert\project\2_www.project.com.crt"

    SSLCertificateKeyFile "D:\wamp\bin\apache\apache2.4.9\conf\cert\project\3_www.project.com.key"

    SSLCertificateChainFile "D:\wamp\bin\apache\apache2.4.9\conf\cert\project\1_root_bundle.crt"

</VirtualHost>

apache version is 2.4.9, using wnmp"s integrated environment.
normal access is fine. Only an exception occurs here when uploading pictures
