I use WinSCP on a PC for two separate sites on two separate servers. I uploaded a few images on one, closed it, and then when I went to the site I was met with:
The connection has timed out
The server at [omitted].org is taking too long to respond.
* The site could be temporarily unavailable or too busy. Try again in a few moments.
* If you are unable to load any pages, check your computer's network connection.
* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
It had worked previously, and it still works on other computers in this house, as well as other computers outside this house.
The other site logs in and updates fine. But this site I can not even log into, WinSCP stops responding.
