Used the new library, but still having problems.

HI again! im the guy from here, and I tried the new library as you said. here is the code(It's just the get example):

/**
 * SYNTAX:
 *
 * T value  = RealtimeDatabase::get<T>(<AsyncClient>, <path>);
 * T value  = RealtimeDatabase::get<T>(<AsyncClient>, <path>, <DatabaseOptions>);
 * 
 * T - The type of value to return.
 * <AsyncClient> - The async client.
 * <path> - The node path to get the value.
 * <DatabaseOptions> - The database options (DatabaseOptions).
 *
 * In case of data filtering and additional request options are required,
 * the DatabaseOptions can be assigned to the get function.
 *
 * Please see examples/Database/extras/FilteringData/FilteringData.ino for how to filter the data.
 *
 * The value of type T returns from sync Get functions is primitype type value or Arduino String.
 *
 * In case of error, the operation error information can be obtain from AsyncClient via aClient.lastError().message() and
 * aClient.lastError().code().
 *
 * Note that the objects used as placeholder (input) that introduced to use in Push, Update and Set i.e.
 * bool_t, number_t, string_t and object_t cannot be used to keep the output value.
 * 
 * The complete usage guidelines, please visit https://github.com/mobizt/FirebaseClient

and i get these until the esp8266 reboots and it shows this:

i think it's because of internet problems.... but can changing the firebase server location help?
thank you!

[mobizt]

HTTP Status 403 means Forbidden.

The request URL is blocked or denied or rejected.

[SkullGamer5]

Yeah i guessed so...
I live in iran and i think the access is blocked because of that. And i did update the ESP8266 core.
I'll try to use a mobile hotspot, and if that didn't work, I'll try to apply a DNS on my ESP8266's connection somehow.
Can you guide me about how to set a custom dns on the connection of my esp8266? Sorry for asking too much ...

[mobizt]

If you are new to Firebase library, you have to read and follow this.
https://github.com/mobizt/FirebaseClient?tab=readme-ov-file#memory-options-for-esp8266

And also, you should try by changing your AP by connecting to the network that can be access to the internet directly e.g. WiFi hotspot from mobile device.

[mobizt]

I forgot to mention about the ESP8266 core update.

You also have to update your ESP8266 Core SDK to the latest version.
