After you assign a Managed country and save, ReachyReach may show "Allocating a dedicated IP" while it assigns that country. Wait, and do not paste a proxy.
Wait for the assignment
The panel also says "Buying {country}. This usually takes under a minute." You can connect LinkedIn once the host is assigned.
Stay on the Proxy tab after you save Managed country.
Read Allocating a dedicated IP. Leave the tab open and wait.
When it succeeds, the panel says Dedicated IP assigned.
Return to LinkedIn and select Connect to LinkedIn.
If it fails, the panel says Could not buy a dedicated IP. Try another country, or save again.
Do not paste a host, port, user, or password on this path. Custom proxy is a separate choice. Allocating is the managed path doing the work for you.
If it stays on allocating
Wait the full minute. Save again only after Could not buy a dedicated IP. Changing country releases the current assignment and pauses LinkedIn until you reconnect. Do not add a second sender to skip the wait.
