@olivinelee Hello! Android clients worked fine in my tests. This could be a DNS or MTU/MSS issue. Please try this fix [1]. Or you may switch to use different DNS server(s) [2]. You may also try IKEv2 mode [3] (recommended) or IPsec/XAuth mode [4].

@hwdsl2 i have already fixed the mtumss accroading to the [1] ,and change dns ,it do not work。 after testing,dns can reslov the website, i think the android doesn't have correct route. but ios ,mac ,windows is ok..

@olivinelee In that case please instead try IKEv2 mode (recommended) or IPsec/XAuth mode, as mentioned above.
