named tunnel is unreliable when multiple sites are exposed

[iamphonghg]

Expected Behavior

all enabled sites should remain reachable through the same named tunnel at the same time.

Actual Behavior

after removing and re-enabling an exposed site, cloudflare sometimes returns 502 for both sites. sometimes only one site works. i cannot make both public sites work reliably at the same time.

i uninstalled yerd and reinstalled 2.0.4 stable, but the same behavior persisted.

Steps to Reproduce the Problem

1. run yerd with two or more linked and secured sites.
2. expose them through one named tunnel.
3. remove one exposed site and enable it again.
4. open both public hostnames.
5. repeat the remove and enable steps.

sometimes both sites return 502 and sometimes only one works.
