ESP8266 server only serves page once, sometimes twice

This is better, but it's still so unreliable as to be useless. If the ESP8266 is going to be used with the Pico's that are going out, major improvements are necessary. A few calls went well... then a call that had worked before failed, and now the server is not answering http requests. Additionally I can't seem to revive the ESP without a hard power cycle. Sometimes I need to do it twice, because it doesn't respond to AT+RST,
