HAProxy can't start

[josephapg]

Windows build number: 10.0.17134.285
Distro: Ubuntu 18.04.1 LTS

Installed HAProxy 1.8.13 from vbernat's ppa and here's what happened when I tried to start it:

[WARNING]: Failed to get the default value of TCP_MAXSEG
[WARNING]: Failed to get the default value of TCP_MAXSEG for IPv6
[ALERT]: Starting frontend http: cannot bind socket [0.0.0.0:80]
[ALERT]: Starting frontend https: cannot bind socket [0.0.0.0:443]

netstat -anp shows no processes listening on port 80 and 443.

You deleted the template. Note second sentence.

cannot bind socket [0.0.0.0:443]

That port is open in in Windows and thus can't be bound. I assume port 80 is too ~!, but there is no (straightforward) way to not bind 443 in windows.~~

[WARNING]: Failed to get the default value of TCP_MAXSEG

An strace would show the setsockopt(2) failing, but it it looks like a soft fail. Hasn't been reported before AFAIK. Suppose this issue can be the landing zone for that.

netstat -anp shows no processes listening on port 80 and 443.

#2249. From the CMD prompt do netstat.exe -an | find.exe "443"

[ed] Guh I mixed up port 443 and 445 in my head. Close/disable/dontrun whatever is consuming 80/443 and see if it fares any better. It might; it might fail for other reasons. The TCP_MAXSEG warning can probably be ignored.

Hi, @therealkenc!

Somehow it works after I did a reset from apps & features.

The TCP_MAXSEG warning can probably be ignored.

Yes, you're correct. Now it works even with that warning.

Thanks for your help!
