zeripathandGitHub a0db075f21 If rendering has failed due to a net.OpError stop rendering (attempt 2) (#19049) ...

Unfortunately #18642 does not work because a `*net.OpError` does not implement
the `Is` interface to make `errors.Is` work correctly - thus leading to the
irritating conclusion that a `*net.OpError` is not a `*net.OpError`.

Here we keep the `errors.Is` because presumably this will be fixed at
some point in the golang main source code but also we add a simply type
cast to also check.

Fix #18629
