When opening a particularly slow loading URL I am getting the following  
error:

Does anyone know how to fix this? I want it to wait longer for the web  
server to respond.

Look in the docs/code and you shall find…

OpenURI wraps net/http and net/https

Looking in net/http finds these accessor methods:

```
# Seconds to wait until connection is opened.
# If the HTTP object cannot open a connection in this many seconds,
# it raises a TimeoutError exception.
attr_accessor :open_timeout

# Seconds to wait until reading one block (by one read(2) call).
# If the HTTP object cannot open a connection in this many seconds,
# it raises a TimeoutError exception.
attr_reader :read_timeout

```

Maybe that would help.

require ‘net/http’

# Lengthen timeout in Net::HTTP

module Net  
class HTTP  
alias old\_initialize initialize

```
    def initialize(*args)
        old_initialize(*args)
        @read_timeout = 3*60 # 3 minutes
    end
end

```

end
