By using example code I got this exception error ( Board ESP01s / DDNS dynu )

Exception 9: LoadStoreAlignmentCause: Load or store to an unaligned address

This because new ESP8266httpClient has changed as lrmoreno007 create a pullrequest sinse 16 Nov 2020

Here is how to modify code.

add between Line 26 and 27 WiFiClient client;

Line 38 from http.begin("http://ipv4bot.whatismyipaddress.com/"); to http.begin(client, "http://ipv4bot.whatismyipaddress.com/");

Line 85 from http.begin(update_url); to http.begin(client, update_url);

After some experimenting I think the issue is that the "http.getString()" command has also changed and it seems to be returning an empty string. I experimented with using 'client.readStringUntil' instead and this does get the response although there are extra characters included. Note: My broadband is supplied by "Three" in the U.K. I did find the esp8266 did not keep resetting when connected via Virgin but can't confirm if it actually worked although I can not imagine why this would make a difference.

Fixed with v1.7.0 release.
