<VirtualHost *:443>
    ServerName one.domain.co.uk

    DocumentRoot /var/www/html/
    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/one.domain.co.uk/cert.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/one.domain.co.uk/privkey.pem
    SSLCertificateChainFile /etc/letsencrypt/live/one.domain.co.uk/chain.pem

    # HSTS (mod_headers is required) (15768000 seconds = 6 months)
    Header always set Strict-Transport-Security "max-age=15768000"

    SSLProxyEngine On
    ProxyPass / wss://one.domain.co.uk:6020/
    ProxyPassReverse / wss://one.domain.co.uk:6020/
</VirtualHost>

This is my apache config. And in every browser I occasionally get the above error ERR_RESPONSE_HEADERS_TRUNCATED .

Does anyone have any ideas as to why this might be an intermittent issue?

Update:
Further info:
I'm using deepstream. Forwarding 433 traffic to 6020. This is in an effort to bypass any client side firewall restrictions.
It's on an apache server.
