copy paste issue using xterm.js from workstation to vm

[tlex]

When I try to paste content from my workstation to a vm while in console with xterm.js, that will work to paste 2-10 lines of code. But if I try to paste more content like 30-100 lines, the session will "disconnect" and eventually reconnect without having paste anything.
Does that have to do wit some buffer limitation ? Can this be edited somewhere ?

works here...
can you post the vm config (qm config ID) or ct config (pct config ID)?
also what is running inside the vm/ct? (meaning where do you paste it to ?)

vm is pfsense (freebsd 12.3)
trying to copy in nano, but also tried ee
copying from a mac on safari, but also tried chrome.
Once paste a big chunk, webconsole will hang, sometime disconnect. I have to go with xvnc or ssh to kill the process.
If I paste to proxmox host web console itself instead of a vm, that works...

I had freebsd configured as :

/etc/ttys:
# name getty type status comments # # If console is marked "insecure", then init will ask for the root password # when going to single-user mode. console "/usr/libexec/getty Pc" xterm on secure # ttyv0 "/usr/libexec/getty Pc" xterm onifexists secure # Virtual terminals ttyv1 "/usr/libexec/getty Pc" xterm onifexists secure ttyv2 "/usr/libexec/getty Pc" xterm onifexists secure ttyv3 "/usr/libexec/getty Pc" xterm onifexists secure ttyv4 "/usr/libexec/getty Pc" xterm onifexists secure ttyv5 "/usr/libexec/getty Pc" xterm onifexists secure ttyv6 "/usr/libexec/getty Pc" xterm onifexists secure ttyv7 "/usr/libexec/getty Pc" xterm onifexists secure ttyv8 "/usr/local/bin/xdm -nodaemon" xterm off secure # Serial terminals # The 'dialup' keyword identifies dialin lines to login, fingerd etc. ttyu0 "/usr/libexec/getty 3wire" vt100 off secure ttyu1 "/usr/libexec/getty 3wire" vt100 off secure ttyu2 "/usr/libexec/getty 3wire" vt100 off secure ttyu3 "/usr/libexec/getty 3wire" vt100 off secure # Dumb console dcons "/usr/libexec/getty std.9600" vt100 off secure xc0 "/usr/libexec/getty Pc" xterm onifexists secure
