Yes, this is the API request that fails to find the image:

```
api.php?callback=jQuery1113038504008506424725_1437475882811&action=query&format=json&iiurlheight=200&generator=search&gsrnamespace=6&continue=&iiprop=dimensions%7Curl%7Cmediatype%7Cextmetadata%7Ctimestamp&prop=imageinfo&gsrsearch=Server&iiurlwidth=300&gsroffset=0&gsrlimit=30
```
It results in: 

```
/**/jQuery1113038504008506424725_1437475882811({"batchcomplete":""})
```

If I add an astericks at the end of t he search-term, it works:


```
api.php?callback=jQuery1113038504008506424725_1437475882811&action=query&format=json&iiurlheight=200&generator=search&gsrnamespace=6&continue=&iiprop=dimensions%7Curl%7Cmediatype%7Cextmetadata%7Ctimestamp&prop=imageinfo&gsrsearch=Server*&iiurlwidth=300&gsroffset=0&gsrlimit=30
```

Results in:

```

When using the astericks, the VE request works, but is repeated endlessly:
