Long access_token and 403 authentication failure

Long token?

I created a pog app and selected all esi permissions.

Authorization, getting a token, updating a token, everything is fine.
/v2/oauth/token (get / refresh)

Any request that requires a token returns a response:
403 {error: ‘authentication failure’}
my request code for example

function getCharactersCharacterIdSkills(characterId, accessToken) {
  const options = {
    method: 'get',
    url: `https://esi.evetech.net/latest/characters/${characterId}/skills/`,
    headers: {
      Authorization: `Bearer ${accessToken}`,

  return axios(options);

I also used EVE Swagger Interface

I think it has something to do with the length of the access_token, because authorization through an application with fewer permissions gives a positive answer.

OMG I’ve been bashing my head against a very hard brick wall on this too…

I have a OAuth2 flow coded up in my web app, and am having issues reading authenticated endpoints.
I’ve followed the guide here OAuth 2.0 for Web Based Applications | esi-docs
And get back an access_token, and I successfully use that token to verify the user:

ACCESS_TOKEN=eyJhbGciOiJ... # 4136 charectors long!

curl 'https://login.eveonline.com/oauth/verify' --header "Authorization: Bearer $ACCESS_TOKEN"  | jq
  "CharacterID": 2116553599,
   "Scopes": "... esi-industry.read_character_jobs.v1 ..." # all the available scopes!

But then attempting to use that same token to get some authenticated API call, it returns error 403 :

curl "https://esi.evetech.net/latest/characters/2116553599/industry/jobs" -H  "accept: application/json" -H  "Authorization: Bearer $ACCESS_TOKEN"

{"error":"authentication failure"}

Your point on Swagger usage was interesting, but I could not reproduce this.
Authorising on there with all the scopes, gives me a access_token that both works on their Swagger UI and on the command line example above.

But I did prove the inverse, that from my application if I requested less scopes, it created a shorter (879 characters) access_token, that does also work on the command line above.

So just need to find the breaking point, and hope I don’t need more scopes than that!
