gmail send error

[mikeshapp]

I'm running HS4 on an HS Zee S2: HomeSeer HS4 ZEE S2 (Upg from HS3ZS2) Edition 4.2.13.0 (Linux)

I setup gmail in the Setup->Mail tab as follows:

- Selected the Use Gmail checkbox
- Enter my full gmail account: e.g. xxxxxxxxx@gmail.com
- Created and entered an app password for my gmail account

I created an event that sends an email but this is what I see in the log when the event occurs.

Exception sending email via GMail (To:xxxxxxxxx@gmail.com, cc:, bcc:, Sub:Leak Sensor, Attach = Method 'System.Net.IPAddress.get_IsIPv4MappedToIPv6' not found.

Any ideas what's causing this?

looks like an IPv4 to IPv6 mapping issue - is your ISP using IPV6 addresses?

Yes but the problem is not that it can't map the IP it's that it can't find the function that it wants to use to do the mapping: get_IsIPv4MappedToIPv6

It might help to update your version of mono, but that is somewhat risky in that it might break something.
Maybe just call HST and ask them first.

That's not the problem but it's close.

I looked in mono's System.dll and found the method is named get_IsIPv4MappedToIPv6, not get_IsIpv4MappedToIPv6 (the P in IP should be upper case, not lower-case as was shown in the error message)

I checked in mono 4.2.0.5 on my HS Zee S2 and in mono 4.7.1 on my HS Pi G3; both with the same issue.

I'll call support next week.

Thanks

Great catch!

The problem was that when I upgraded my Zee S2 from HS3 to HS4, it doesn't update mono from 4.2.05 and HS4 emails don't like mono 4. I had to re-image the Zee with the latest HS4 and restore my configuration from backup.

It's now running HS4 4.2.13.0 with mono 6.12.0.182 and, finally, successfully sends emails through gmail.
