NFC module seems to be disconnected and does not work anymore

[drstil]

Since I have done the update to version 0.4.1 (from version 0.3.1 or 0.3.11) I have issues with NFC module becomes not available anymore and only a restart (of HomeKey-ESP32) could make the scanning available again. This happens after a lot of hours or sometime after few days, but did not find any reproducible for this. I also checked the serial logs, but nothing really reproducible is seen. Once I had the following in the logs:

...
(12548969) MAIN: nfc thread entry > *** PASSIVE TARGET DETECTED ***
(12549167) HKAuthCtx: HKAuthenticationContext > Initialization Time: 171 ms
(12549355) HKAuthCtx: authenticate > Endpoint authenticated, transaction took 187 ms

(13594472) MAIN: nfc thread entry > *** PASSIVE TARGET DETECTED ***
(13594480) PN532 SPI: Received Error Frame - TFI: 7f CMD:81
(13594481) PN532: STATUS NFC: -5
(13594481) MAIN: nfc_thread_entry > Invalid Response, probably not Homekey, publishing target's UID
(13956020) PN532_SPI: PN532:: INVALID HEADER

I also tried with higher log levels for both HomeSpan and HomeKey, but could not get anything.

Not available means, that the HomeKey web interface is reachable, but when scanning a nfc tag, nothing is happening (in the serial logs).
I tried different NFC modules (all same manufacturer (Elechouse)), but all lead to same issue. I think this is all information I could give.

Any ideas, what could cause the issue?
