Just the default HttpClient setup. using (var response = await client.PostAsync(new Uri (baseUrl + "/api/Account/Prelogin"), content)) { The text was updated successfully, but these errors were encountered: You didn't initialize the cache by calling cache() after apply, see the readme, of okhttp documentation, it is required when using overrideServerCachePolicy, you also need to call forceCacheWhenOffline() if you want to avoid using the network when offline. The 504 response is automatic response from OKHTTP when request header only-if-cached is provided and there is no response in cache, this is what happens when NetworkMonitor#isOnline returns false, so are you sure you were online? We are using a separate reverse proxy that uses the reverse proxy URL. Problems with DNS resolution Issue #3919 square/okhttp at com.squareup.okhttp.Call$ApplicationInterceptorChain.proceed(Call.java:228) Any way the matter of concern is not the ability to use Polly, but the ability to understand the core issue of exception from .NET Standard shared code. Dns.kt line 49 @muhaym I am not familiar with Polly, but the exception will come through as Java.Net.UnknownHostException, a type you won't have a reference to in your netstandard project.

For more info about this read this article. ifIndex = 25 @UnreachableCode I am wondering if you have some dependency using okhttp. When trying to download the offline map, I get the following error message. I will give you feedback if that doesn't solve the problem. dnsRecords={hostname=router, model=DE2600, mac=80:d7:00:bc:b2, wifi=000156, A code sample or steps: SM-G986N, SM-G991N. at com.android.okhttp.internal.http.HttpEngine.connect + 392(HttpEngine.java:392) Before you begin, you must always remember to: N.B: If you want to depend on your server's caching protocol for online and offline caching, then don't read the 2 solutions. I suspect that Apple is taking advantage of this from the HTTP spec in section 9.5 about POST: Responses to this method are not cacheable, unless the response .compose(rxDnssd.queryRecords()) Did you find okay in other manufacturers devices like pixel(Android 11) also? at java.net.InetAddress.getAllByName + 1154(InetAddress.java:1154) It's down below. at com.squareup.okhttp.internal.http.RouteSelector.nextProxy(RouteSelector.java:193) When an electromagnetic relay is switched on, it shows a dip in the coil current for a millisecond but then increases again. at java.net.Inet6AddressImpl.lookupAllHostAddr + 105(Inet6AddressImpl.java:105) {Collections$UnmodifiableMap$UnmodifiableEntrySet$UnmodifiableEntry@5860} Because I have got the response when I am online.

Below is what I use in the right bit of my Apache config to target the whole of my API because as it happens I don't actually want to cache anything, even gets. D/Log: Content-Length: 122 On the other hand, if the server auto-includes a valid Date header, then you could theoretically omit Cache-Control too and rely on Expires only. The correct minimum set of headers that works across all mentioned clients (and proxies): The Cache-Control is per the HTTP 1.1 spec for clients and proxies (and implicitly required by some clients next to Expires). Already on GitHub? I don't have any reference to Okhttp, but not sure how okhttp ends up in logs like the report above. //DbxRequestConfig config = new DbxRequestConfig("dropbox/java-tutorial"); /t5/Dropbox-API-Support-Feedback/Permission-Denied-Okhttp-Dispatcher/td-p/195862, https://developer.android.com/guide/topics/security/permissions.html#permissions. debugMsg("--RxDNSSD zeroconf-- service remove $bonjourService") Getting this Error Unable to resolve host XXXXXX Comunidad Esri Colombia - Ecuador - Panam. Once an UnknownHostException is returned, the user continues to receive the same error unless the app is reinstalled or the device is rebooted.
