Reverse proxy MUX parameters

[pulsarice]

Hi
I receive this error on my portal server from time to time
[Error] common/mux: failed to read metadata > common/mux: invalid metalen 5891
and this on my bridge server
[Error] common/mux: unexpected EOF > common/mux: failed to read metadata > common/mux: invalid metalen 5891
Bridge is connected to portal servers via Cloudflare CDN with vless+ws+tls.
Per Xray-core documentation MUX is enabled by default on reverse proxies and I didn't enable it on my bridge server outbound.

Are there any user adjustable MUX parameters for reverse connections?
