UPDATE AND MORE DETAILS:
We are requesting our own web API using these two functions:
GetAuthentication()
() =>
let
output = Json.Document(
Web.Contents(
#"www adresse",
[
RelativePath ="/OmegaAPITest/Authentication/Token",
Headers=[Accept="application/json", #"Content-Type"="application/x-www-form-urlencoded;charset=UTF-8"],
Content=Text.ToBinary("grant_type=password&username="&#"Brugernavn"&"&password="&Adgangskode&"&client_id=2E54A038A9E598FD325F592EBA63EAD12210DC815907D4022210DC815907D502")
//Query=[r=Number.ToText(Number.Random())],
]
)
)
in
output
GetRequest(...)
(request as text) =>
let
authentication = GetAuthentication(),
output = Json.Document(
Web.Contents(
#"www adresse",
[
RelativePath = "/OmegaAPITest/v2/" & request,
Timeout=#duration(0,1,0,0), //#duration(days as number, hours as number, minutes as number, seconds as number) as duration
Headers=[#"Authorization"= "Guid " & authentication[access_token], #"Content-Type"="application/json; charset=utf-8"]
]
)
)
in
output
PostRequest(...)
(request as text, content as text) =>
let
authentication = GetAuthentication(),
output = Json.Document(
Web.Contents(
#"www adresse",
[
RelativePath = "/OmegaAPITest/v2/" & request,
Timeout=#duration(0,1,0,0), //#duration(days as number, hours as number, minutes as number, seconds as number) as duration
Headers=[#"Authorization"= "Guid " & authentication[access_token], #"Content-Type"="application/json; charset=utf-8"],
Content=Text.ToBinary(content)
]

We have extend our API to be able to cache the response for large data calculation - all this to overcome the problem.
Refreshing data on desktop alway work, but not then we publish it on the service and try refresh using the service.
For now it seems to work hvis API have caches some data for faster response, but only stabil if we add som delays - see new functions below:
GetRequestWithDelay(...)
(request as text, delay as number) =>
let
output = Function.InvokeAfter(() =>
let
authentication = GetAuthentication(),
response = Json.Document(
Web.Contents(
#"www adresse",
[
RelativePath = "/OmegaAPITest/v2/" & request,
Timeout=#duration(0,1,0,0), //#duration(days as number, hours as number, minutes as number, seconds as number) as duration
Headers=[#"Authorization"= "Guid " & authentication[access_token], #"Content-Type"="application/json; charset=utf-8"]
]
)
)
in
response, #duration(0,0,0,delay))
in
output
PostRequestWithDelay(...)
(request as text, content as text, delay as number) =>
let
output = Function.InvokeAfter(()=>
let
authentication = GetAuthentication2(),
response = Json.Document(
Web.Contents(
#"www adresse",
[
RelativePath = "/OmegaAPITest/v2/" & request,
Timeout=#duration(0,1,0,0), //#duration(days as number, hours as number, minutes as number, seconds as number) as duration
Headers=[#"Authorization"= "Guid " & authentication[access_token], #"Content-Type"="application/json; charset=utf-8"],
Content=Text.ToBinary(content)
]
)
)
in
response, #duration(0,0,0,delay))

Hi @shvitani ,
It might caused by transport layer security (TLS) for Power BI. Check the topic below and see if it helps.

Hi Jay,
Thanks for your reply, I have almost tried everything related to the transport layer security (TLS), nothing helped - please note that it's not on every refresh it crash, but most of the time.
Hi @shvitani ,
If this situation happens completely randomly, it will be difficult to debug the issue.
You could try to open a support ticket. It is free if you have a Pro account.
Go to https://support.powerbi.com. Scroll down and click "CREATE SUPPORT TICKET".
Best Regards,
Jay
Hi Jay,
Please note, we have added more details - do you think we need to create a support ticket? 🙂
Hi @shvitani
Is the Gateway up-to-date?

Hi Amine,
