Web UI timeout over tail scale #12748
Description
Description
When working through tail scale vpn to connect to the web interface, repeated prompts (2 are enough, as long as the first one is long enough) lead to "failed to fetch" error on prompt send. The prompts wont appear until page is manually refreshed.
The error is given due to a synchronous api that shouldn't have been used already discovered in a previous issue (but that one is an AI text wall, and since I encountered this myself I am recreating an issue).
Plugins

OpenCode version

Steps to reproduce
- Run web through a "greedy" network stack (tail scale)
- Run a task or two that run for more then 30 seconds or so.
