Email Notification Causes Reboot if Internet is Offline

[ThomasB]

Yesterday my ISP went offline for several hours. During the outage I discovered that ESPEasy consistently reboots when it attempts to send an email notification. In my case, it created a boot loop because the device sends an email when WiFi connects.

Here's the serial log (Serial Log Level: None):

THIS IS AS FAR AS IT GOES, THEN REBOOTS AGAIN

Is this a known problem? Is there a stable test build I can use that has fixed this?

Nope not a known problem, but I can imagine where it might fail.
Likely it is running out of memory as those libraries for SSL are really a mess regarding memory management.

[ThomasB]

I could ping 8.8.8.8 to test for web connectivity. Then I could apply a conditional to the notify rules. But the ping plugin is not in the collection_B_ESP32 builds. And I want to avoid custom builds.

Are there any other tricks I could use to accomplish the same thing? Or even better, is this issue something that will probably be fixed in the next couple months?

It will likely be fixed in the next couple weeks/months.
I'm currently a bit unsure about the amount of available time, as there is just so much to do right now (not only ESPEasy), which makes planning extremely hard.

[ThomasB]

I fully understand about the time constraints.

In the meantime, if anyone has a clever workaround (similar to the ping idea) then please share.
